  All IFMIF - EVEDA RFQ modules were completed in summer 2015. In the previous year the last three modules were RF tested at LNL at nominal power up to cw operation. At the beginning of this year all the modules were assembled in three 3.3 m long super-modules structures that were shipped to Japan. RFQ was then installed and tuned with provisional aluminum tuners and end plates to nominal frequency and field distribution. Replacement of movable aluminum components with copper fixed ones increased cavity quality value not affecting field flatness and frequency.

THCAMH06 Gantry Free Transport Line for a Proton/Ion Therapy proton, ion, target, radiation 120
 
  • M.M. Kats
    ITEP, Moscow, Russia
  
  For a long time a gantry was considered as a mandatory element for proton/ion therapy facility. However medics from MGH (Boston) suggested alternative concept which leads to decrease both cost and size of the facility*. The concept is based on the following provisions: - immovable isocenter; - active scanning of a target volume; - different positions of patients at different fractions: - using CT on the place of irradiation after each change of positions of the patient for improvement plan; - using small change direction of the beam (like ±100). The "Planar isocentric system" developed by author can be used to enlarge the flexibility of the concept**. It's relatively chip, small and can be realized for short time. It can be used for treatment for 90% of localizations. The system can replace gantry in centers of proton/ion therapy providing significant decreasing of treatment price. The details of the system are presented and discussed.

TUPSA024 On Stabilization of Systems of Linear Equations with Linear Increasing Time Delay by Observation feedback, synchrotron, acceleration, damping 261
 
  • O.N. Chizhova, A.P. Zhabko
    Saint Petersburg State University, Saint Petersburg, Russia
  
  Differential-difference equations with time delay are often used in mathematical models describing the dynamics of beams of the charged particles. For example linear equation of the second order with a constant time delay describes in the smoothed approach dynamics of a beam of the charged particles in synchrotrons with a feedback system. However the time delay cannot always be considered constant. The time proportional delay can occur at acceleration of beams of the charged particles in the cyclotron. It should be noted that such time delay is unbounded and well known approaches are not applicable for stability analysis such systems. The stabilizing control for the system of linear equations could be constructed by the information on a state vector of the system. Sometimes the state vector is unknown but we know some linear combinations of its components. Then there is a problem on construction of the stabilizing control with incomplete information. In this paper we investigate a possibility of stabilization of system of linear equations with time proportional delay by the linear observation. Using the sufficient conditions of asymptotic stability of system of linear equations with linear increasing delay we obtain some conditions of existence of the asymptotic evaluation system of the original system. Then we use the asymptotic evaluation system for the construction of the stabilizing control and derive the sufficient conditions for the existence of such control.

  The problems of the trajectories constructing for field electrons and emission images simulation are considered. As an approximation of the emitter shape an explicitly and implicitly defined surfaces are selected. Hyperboloidal, ellipsoidal and paraboloidal models are studied. Also an equipotential surface of the charged sphere-on-orthogonal-cone system is used. A simple solution of the field distribution problem is allowed to formulate the Cauchy problem for the motion equations. The shape of the anode (the projector microscope screen) can be selected in any desired form. Achieving a screen by electrons is performed with dense output technique in numerical approach to the solution. The distribution of the work function on the cathode surface is obtained. The trajectories for the projection of the field emission activity as the image are used.

  The problem of simultaneous optimization of the ensemble of trajectories and some selected trajectory arises in the research of the charged particle beam dynamics. The present work suggests the use of a smooth functional for the evaluation of the selected trajectories and a minimax functional for the evaluation of the dynamics of the beam of trajectories.

  The paper is devoted to quasiperiodic beam dynamics investigation. Particle density is modeled by trigonometric polynomial. Space charge field is represented in the similar form. This approach is applied to beam dynamics investigation in klystron-type buncher. Numerical algorithm of polynomial coefficients calculation from the positions and impulses of model particles is formalized. As a result Coulomb field intensity is expressed in the form of integral over the set of particle phase states. Integro-differential beam evolution model is presented. Analytical expression of the variation of beam dynamics quality criterion is obtained. It makes possible directed methods using for beam dynamics optimization.

  • M.Yu. Balabanov

  Modern research process of scientific problems often requires large computational resources. To solve them we have to use distributed computing systems. Researcher groups need to use them simultanieously and mostly remotely. The paper describes build of the distributed system for collaborative research process. As example was chosen a problem of the optimization dynamics charged particle beams using high-performance computing systems. The solution of many topical tasks leads to nonlinear optimization problems for example the controlling beams of charged particles. Optimization is performed by minimizing some quality functional the choice of which is a corollary fact that the control functions which provides a functional minimum should determine the accelerating structure with the desired characteristics. The problem is usually formulated as finding the control functions for which the controlled system satisfies the given constraints. There is a necessity of the quality functional choice which ensures the problem solution. Research objectives: the development of a distributed information-computational system for the analysis of charged particle beam dynamics.

WEPSB012 On The Beam Dynamics Simulation In The Injection System injection, simulation, software, rfq 382
 
  • A.D. Ovsyannikov, S.A. Kozynchenko, V.A. Kozynchenko
    Saint Petersburg State University, Saint Petersburg, Russia
  
  When developing a particle accelerator for generating the high-precision beams, the injection system design is of importance, because it largely determines the output characteristics of the beam. At the present paper we consider the injection systems consisting of electrodes with given potentials. The design of such systems requires carrying out simulation of beam dynamics in the electrostatic fields. For external field simulation we use the new approach, proposed by A.D. Ovsyannikov, which is based on analytical approximations, or finite difference method, taking into account the real geometry of the injection system. The software designed for solving the problems of beam dynamics simulation and optimization in the injection system for non-relativistic beams has been developed. Both beam dynamics and electric field simulations in the injection system, that use analytical approach and finite difference method have been made and the results presented in this paper.

WEPSB013 On Approach for Resonant Frequency Tuning in Drift Tube Structures on the Designing Stage cavity, simulation, target, electron 386
 
  • I. Skudnova, V.V. Altsybeyev
    Saint Petersburg State University, Saint Petersburg, Russia
  
  Current research considers the interdigital H-mode linear resonant accelerator with drift tubes mounted inside the cavity. The focus of the study has been on the dependence of resonant frequency on the parameters of the geometry. Since Alternating-Phase-Focusing (APF) type of accelerator is investigated, the efficiency of the operation depends on the synchronization of the charged particle velocity and accelerating field oscillations. Researchers can control it by the variation of longitudinal size of the cells of the structure (periods). On the other hand, the effective performance of the resonant system requires the equality of resonant frequencies of its cells, because it affects the uniformity of accelerating field distribution along the axis. The diversity of cells longitudinal sizes causes the deviation from the particular value of the resonant frequency. This aberration can be eliminated by the adjustment of other geometry parameters: period's length, gap ratio and drift tube diameter. We have conducted the study to analyze the relation between resonant frequency and these values. Using the this dependency we can tune the geometry parameters of each period in the structure. We first create the computer-aided design (CAD) geometry model of the accelerator cavity. Then, using Comsol Multiphysics, the platform for physics-based modeling and simulation, we conduct the calculation of resonant frequencies.

  The article considers the problem of forming a predetermined distribution density of the beam (in the phase or configuration space) in a periodic channel. The proposed approach is based on a method of constructing a beam mapping in the form of a truncated series consisting from matrices up to necessary order of nonlinearities. Similar approach allows us to formulate the given task as an optimization problem for some special functionals, created from parameters of the accelerator. Some results of the testing tasks are demonstrated.

  We start with a qualitative approach based on the detailed analysis of smoothness classes of the underlying functional spaces provided possible evaluation of the dynamical aperture in general nonlinear/polynomial models of particle/beam motion in accelerators. We present the applications of discrete multiresolution analysis technique to the maps which arise as the invariant discretization of continuous nonlinear polynomial problems. It provides a generalization of the machinery of local nonlinear harmonic analysis, which can be applied for both discrete and continuous cases and allows to construct the explicit multiresolution decomposition for solutions of discrete problems which are the correct discretizations of the corresponding continuous cases.

  In this work the survey of methods for high intensive beam dynamics is given. As an alternative to them the approach based on envelope dynamics was used. This method is focusing on the use of the matrix form for Lie algebraic methods for calculating the beam dynamics in the presence of self-field of the beam. In particular, the corresponding calculations are based on the predictor-corrector method. Pros and cons of using described approach on hybrid systems are discussed.

  Problem of the optimal parameters choice for the charged particles beam is considered. The beam is characterized by the set of control parameters and multiple parameters which characterize its quality. So multiple criteria of optimization should be taken into account. Among possible criteria of optimization following ones should be mentioned: energy, intensity, biological efficiency and so on. It is assumed that in general case choice of the control parameters which is optimal for all criteria is not possible. The problem is formulated as the conflict control problem. The case is considered when parameters which should be optimized forms the vector. Finding of the compromise solution is considered. The method and computing algorithms are proposed. Present work is further extension of *.

  It is known, hyperthermia is widely used to improve the efficiency of cancer treatment. Local hyperthermia is a method where only tumor is heated, on the other hand healthy tissues are protected from overheating. It was proposed to use an array of eight independently phased dipoles operating on 100-150 MHz to focus the RF energy in deep-situated volume of 30-50 mm size. But the problem of non-invasive temperature measurement should to be solved for correct operation of the local thermoradiotherapy systems. Conventional invasive thermometry devices as thermocouples, thermistors or Bragg optical sensors can not be widely used because of serious risk of the cancer cells transport to healthy tissues. Radiothermometry or acoustic thermometry can not be used for tissues located deeper than 5-7 cm. As known electrodynamics characteristics of tissues depend on temperature. It was proposed to use this effect for active radiothermometry in local hyperthermia. Two opposite RF dipoles can be used as generator and receiver of pick-up signal. It was shown by simulations that such method can be used for thermometry of deep-situated tissues and have high resolution. Results of simulation will present in report.

  Hyperthermia combined with radiotherapy (thermoradiotherapy) or with chemotherapy is one of promising approach to improve the cancer treatment efficiency. The treatment of deep-situated tumors is a problem which can not be solved by means of traditional facilities developed for whole-body or regional hyperthermia because of overheating of healthy tissues and blood. A cylindrical array of independently phased dipoles was proposed to focus electromagnetic energy in deep-situated tumors. It was early shown by simulations that array of eight independently phased dipoles operating on 100-150 MHz can be used to focus energy in an ellipsoid of 30-50 mm in size. Later the laboratory model of thermoradiotherapy facility was developed and constructed and series of experiments were carried out. Results of experiments and its comparison with simulations will discuss in report.

  Main problems of accelerator-driver design for ADS are considered. Accelerator-driver should meet additional requirements in comparison with accelerators for other purposes: - high neutron production rate; - higher reliability; - continuous operation for more than 5000 hours; - possibility of accelerator parameters adjustment to regulate ADS power level. Different types of accelerators were analyzed taking into account the mentioned features and the fact that the most prospective way of ADS application nowadays is transmutation. It's shown that the most preferable accelerator type is proton linac. Also it's marked that for demonstration facilities accelerators with lower requirements and correspondingly cost can be used.

  Neutron generators NG-10 and NG-10M with a neutron yield of 1*1010 n/s and 2*1011 n/s respectively have been designed in the JSC "NIIEFA". The generators are high-voltage accelerators with target devices intended for installation and effective cooling of Ti-T/Ti-D targets of different diameters. A duoplasmotron with a beam current up to 5 mA is used in the NG-10 generator, and the NG-10M employs a microwave ion source providing the beam current up to 10 mA. The power supplies, which are under high voltage, are controlled via fiber optic communication lines. Deuterium ions produced in the ion source are accelerated up to 150 keV in a sectionalized accelerating tube, separated in mass with an electromagnetic mass-separator and focused onto a target with a doublet of electromagnetic quadrupole lenses. The generators are equipped with several lines to transport the beam to targets, which can be placed in separate rooms. In addition to a high and stable in time yield of neutrons when operating continuously, the generators provide the pulsed mode with a smooth variation of the pulse width from 2 mks up to 100 mks and pulse repetition rate from 1 Hz up to 20 kHz.

  The basic possibility of creation of high speed cryogenic monodisperse targets is shown. According to calculations at input of thin liquid cryogenic jets with a velocity of bigger 100 m/s in vacuum the jets don't manage to freeze at distance to 1 mm and can be broken into monodisperse drops. Drops due to evaporation are cooled and become granules. High speed cryogenic monodisperse targets have the following advantages: direct input in vacuum (there is no need for a chamber of a triple point chamber and sluices), it is possible to use the equipment of a cluster target, it is possible to receive targets with a diameter of D < 20 mkm from various cryogenic liquids (H2, D2, N2, Ar) with dispersion less than 1%, the high velocity of monodisperse granules(> 100m/s), exact synchronization of the target hitting moment in a beam with the moment of sensors turning on

  Pulsed deflecting magnet (kicker) project was worked out in BINP (Budker Institute of Nuclear Physics). The kicker design task is: impulsive force value is 1 mT*m, pulse edge is 5 ns, and impulse duration is about 200 ns. The unconventional approach is for plates to be substituted by a set of cylinders. Obtained magnet construction allows controlling field homogeneity by changing currents magnitudes in cylinders. Furthermore we demonstrated the method of field optimization. In addition the harmonic components measurement technique was considered and the possibility to control harmonic components value was shown.

  At this time BINP are working on material research for the ITER project. The spatial inhomogeneity of deformation is the scope of this study. An optical pattern generator GOG-1001 that increases the energy of monochromatic light source is used in such experiments. GOG-1001 is powered by a high-voltage quasi-momentum PS that feeds energy stored in a capacitor bank to the generator's pump tube. A pulsed voltage source driven by FPGA controller module has been developed. The module controls correct bank charge, monitors tube's current and voltage as well as calculates the energy supplied to the bank and activates the generator. A hardware bank overcharge protection prevents the pump tube from failure. The developed source has two control modes; remote - workstation and manual - front panel. The source control logic is based on FPGA while communication and date computing is processed by a digital processor and a graphic display.

  OCEM and ENEA gained a wide experience in the design and experimental characterization of fast and accurate switching systems for high DC currents, as required to supply magnets and superconductors. The exploited idea consists in inserting an electronic switch in parallel to a light electromechanical switch in air to combine the benefits of both devices. The electronic switch is turned on and off to support the electromechanical commutations limiting their jitter and the arcs that would reduce the system lifetime. During the already performed tests, DC currents up to 20 kA were diverted in less than 100 mks with good repeatability. In case of emergency, the current can be interrupted in few tens of milliseconds. A resistor can be inserted in parallel to the switch to discharge inductive loads or to produce desired overvoltages (a voltage up to 5 kV was reached in this configuration). Specific circuits were designed to preserve the components from transient voltage overshoots. This switching system is expected to work for 10000 operations without major maintenance. The developed solutions may be extended to many relevant applications as particle accelerators and HVDC networks.

  Insulated core transformer (ICT) high voltage power supply is an ideal model for industrial radiation accelerator at energy below 1MeV. Compared to the traditional scheme, a novel ICT high voltage power supply was put forward. Conventional silicon steel sheets were replaced with manganese zinc ferrites, raising working frequency from 50Hz to thousand hertz. Magnetic structure was changed from three-phase structure to four-phase structure. Accordingly, excitation voltage was changed from three-phase sinusoidal wave to square wave. Polyimide was chosen as insulation material instead of teflon or mica. A prototype of 400kV/50mA was designed, simulated and verified with the aid of finite element analysis software. To optimize the voltage distribution, corresponding flux compensation methods were raised to solve the problem of flux leakages.

  Integrated inspection method of motor transports was suggested based on linear electron accelerator and neutron generator, which helps to detect substances forbidden for carrying, including explosives, narcotic drugs and fissionable materials. The linear high-frequency electron accelerator is a source of X-ray bremsstrahlung. The result of scanning is an introscopical image of a motor transport with color-selected suspicious substances. The neutron activation analysis of these substances with neutron generator as a neutron source lets detect elemental substance composition as well as identify explosives or narcotic drugs. This article contains accelerator specifications, which lets implement suggested method.

1.Previous systems of energy and current stabilization are based on analog PID-controllers. They provide good stability at sufficient speed-work. 2.Increased requirements of technological lines to the speed of the accelerator injection to set-up parameters and introduction of technological lines, in which the accelerator is a slave device and should within the shortest possible time to respond onto the changes of operation input parameters, forced us to find the way of stabilization systems improvement. 3.New stabilization system is able to provide current output speed up to 5mA/sec, at required energy stability. 4.Digital-to-analog stabilization is produced as a superstructure on the existing system and is made as a source code added into the basic accelerator control program. This approach enables to modernize simply the existing accelerators. The code itself is two independent parts. The first part is the current beam corrector, which calculate the derivate (current speed) at a time and aims to hold it in set-up range, taking into account the difference of the tasks and the necessity of cathode warm up. The second part is a energy compensator. It adds the current derivate into accelerator energy channel, reducing the energy settlements at once. 5.Present system passed through the testing and it is already installed onto ELV-0.5(0.5MeV, 100mA) accelerator in Qingzhou (a/m tyre production) and onto ELV-8(2.5MeV, 40mA) accelerators in China for cable insulation treatment.

  The report discusses development of the host-based data acquisition system to control the accelerator. We consider modes of timing and allocation of operations of the system node. The time of any working cycle, rate of a data flow and an amount of serviced tasks are coordinated with characteristics of the node. Estimations of the readout rate of the data and the waiting time demonstrate the system efficiency. The data acquisition technique has been developed to provide checking of pulse parameters and control the linac LUE-200 of the neutron source IREN*.

This paper presents general description of hardware and software of the neutral beam injector control system. The system is developed for control of the neutral beam injector which operates with 15-25 keV deuterium and hydrogen beams of 2 s maximum duration. It performs injection parameters calculation according to the desired beam power vs time curve, synchronizes and protects the injector subsystems and acquires its data during the shot. It also controls the injector operation between the shots. The system is based on an industrial computer with National Instruments PCIe boards: two PCIe-7842R reconfigurable input-output modules and a PCIe-6323 data acquisition module. An in-house developed interfacing module (cross-box) as well as serial to fiber optic converters are used for galvanic isolation and electrical compatibility with the injector subsystems. User interface software and PCIe boards programmable logic firmware are implemented in LabVIEW. Injection calculations and results acquired are represented with MATLAB.

  The Linear Induction Accelerator LIA-20 is being created at the Budker Institute of Nuclear Physics. Waveform monitoring system (WMS) is an important part of LIA-20 control system. WMS includes "slow" and "fast" monitoring subsystems. Three kinds of digitizers have been developed for WMS. "Slow" subsystem is based on ADCx32. This digitizer uses four 8 channel multiplexed SAR ADCs (8 us conversion cycle) with 12-bit resolution. Main feature of this module is program configurable channel sequencing, which allows to measure signals with different timing characteristics. Two types of digitizers are involved in "fast" subsystem. The first one, ADC4x250-4CH, is 4-channel 250 MSPS digitizer. The second one, ADC4x250-1CH, is single channel digitizer with sample rate of 1 GSPS. Resolution of both devices is 12 bit. "Fast" modules are based on the common hardware. This paper describes hardware and software architecture of these modules.

The new source of epithermal neutrons*, designed for boron neutron capture therapy (BNCT)** of cancer in oncology clinic, was proposed and developed in Budker Institute of Nuclear Physics. This method of treatment is effective against several currently incurable radioresistant tumors, such as brain glioblastoma and melanoma metastases. The neutron source includes a new type of accelerator: accelerator-tandem with vacuum insulation, lithium neutron generating target and neutron beam shaping assembly. Current accelerator produces a stationary 5 mA proton beam with 2 MeV energy, but this is not sufficient for therapy on humans. For conducting the experiment on humans it is necessary to create a new power rack for the ion source. The report summarizes results of the development and implementation of new power rack, with remote control and data collection systems, to reach 15 mA beam current. This system will increase the proton beam current and, as a result, the neutron yield, that is needed to heal people.

Nonlinear oscillatory systems are widely applied for the modeling of charge particles motions in cyclotrons in neighborhoods of equilibrium orbits. They are also used for the analysis and synthesis of magnetic control devices. An actual problem for such systems is stabilization of their operating modes. In this report, analytical and numerical investigations of stability of the equilibrium position for a nonlinear oscillatory system are presented. The system can be treated as a mathematical model of magnetic suspension control system of a gyro rotor. A delay in the feedback control scheme and dissipative forces occurring due to energy losses at the interaction of the magnetic field with currents in the control loops are taken into account. Two approaches to the synthesis of stabilizing controls are proposed. The first one is based on the using of gyroscopic control forces. It is applicable in the case of essentially nonlinear homogeneous dissipative forces. The second approach is efficient for systems with linear dissipative forces. For this case, potential control forces are constructed. With the aid of a computer simulation of dynamics of closed-loop systems, a comparison of these approaches is fulfilled, and their features and conditions of applicability are determined.

  The charged beam moving in the accelerator is modelled by particle-in-cell method. The control with delay in the connection canal is simulated by the after-effect. Thus, the model is described by system of the differential equations with delay. We observe and estimate changes of particles coordinates in the cross-section of the accelerator. It is supposed that initial conditions are the set with random error and we have chance of updating the solution in periodic timepoints with the same error. The dependence between the estimate dispersion and the measuring error dispersion is recieved.
