Yu Huazhong University of Science and Technology, State Key Laboratory of Advanced Electromagnetic Engineering and Technology,, Hubei, People's Republic of China
	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.

	Funding: Budker Institute of Nuclear Physics, Novosibirsk, Russia. 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.

Currently nuclear medicine is a high-tech field. Its development requires solutions of problems related both to the improvement of hardware and computer processing of the information obtained in the course of study. The basic types of hardware of nuclear medicine are gamma cameras and single photon emission computed tomography (SPECT), positron emission tomography (PET) and hybrid scanners (SPECT/CT, PET/ CT). The methods of SPECT data processing include analysis of static, dynamic, tomographic and ECG-gated images. The PET data reconstruction software restores the three-dimensional distribution of the radiopharmaceutical in the body. Performance of iterative methods increases with the use of modern graphics processors. Three-dimensional imaging allows a detailed analysis of the study area. The software also implements a fusion imaging of SPECT/CT, PET/CT scans performed in the same coordinate system. An application of data flow model in medical software development is considered. Web-based imaging front-end of storage and processing system is presented.

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.

The system of beam correction for European XFEL includes about 400 precise current sources. Before including in XFEL equipment the every current source must tested and verified in concordance with specifications. For this purpose there was developed the automated system allowing to test up to 7 current sources simultaneously. The system consists of stand and software that written for linux OS. The stand was equipped by test loads, which emulated the real load, by precise DCCT and by precise analog-to-digital converters with CANbus interface. During testing the current in each current source was changed and digitized in concordance with different algorithms. The duration of typical session was 25 hours. The specific software was developed for this stand. It provides testing process, collecting and storing the primary information and displaying the first information. There are addition utilities which allows to make different analyzes in off-line mode using data accumulated during tests. The article provides a detailed description of the stand and main results.

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.

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.

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.

There is the accelerator-tandem at the Nuclear physics institute in Novosibirsk which is suitable for malignancies treatment such as glioblastoma and melanoma using BNCT methods. There are different gamma spectrometry diagnostics which apply under this project. One of these is used to determine the parameters of the neutron beam. The method is to irradiate a set of activation foils with neutrons. Then measure the gamma-spectrum of foils using gamma detector. Based on these data it can be calculated the activity of foil, as well as the amount and the energy of neutrons. For data processing of these diagnostics there was developed a software which is used for convenient display of gamma-spectrometer data and the activity of the foil. Software allows setting a canal calibration and the sensitivity calibration which is needed to calculate the foil activity.
