	Y.D. Chernousov ICKC, Novosibirsk, Russia I.M. Ikryanov, I.V. Shebolaev ICKC SB RAS, Novosibirsk, Russia
	New data on the development and experimental investigation of the RF accelerator based on the 9-cavities parallel-coupled accelerating structure that is equipped with a high-frequency grid-controlled electron gun are presented. Accelerating structure, injection system and focusing system are improved. Previously observed second emission resonant discharge - multipactor is suppressed by increasing the field amplitude in the structure first cavity and using the protector. The parameters of the accelerated beam close to the design ones, i.e. electron energy up to 8 MeV, capture to the acceleration mode up to 100%, were received. Capture is provided by the RF electron focusing of the microwave field structure with usage of the magnetic focusing system based on permanent magnets and RF grid control in the electron gun.

WEPSB012	On The Beam Dynamics Simulation In The Injection System	simulation, software, controls, 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.

	Since 1997, different variants of bunching systems have been used at the axial injections of FLNR cyclotrons to increase ions capture into acceleration efficiency. Combination of two single gap Sine and Line bunchers are used at the axial injections of U400 and DC110 cyclotrons. Since 2015, a single gap double RF harmonic buncher has been installed into the upper part of the U400M injection in addition to the lower sine buncher, the experimental results will be presented. For the HV axial injection of the new DC280 cyclotron, two variants of polyharmonic bunchers will be used: a multigap buncher and a single gap one.

WEPSB046	A Cyclotron Complex for Acceleration of Carbon Ions	cyclotron, ion, extraction, acceleration	467
	V.L. Smirnov, S.B. Vorozhtsov JINR, Dubna, Moscow Region, Russia
	An accelerating complex for hadron therapy is proposed. Facility consists of two superconducting cyclotrons and is aimed to produce beams of 12C⁶⁺ ions with energy of 400 MeV/nucleon. Accelerator-injector is a compact 70 MeV/nucleon cyclotron. Main machine is separated sector cyclotron consisting of six magnets. Basic features of the main cyclotron are high magnetic field, compact size, and feasible design of a magnetic system. The advantages of the dual cyclotron design are typical of cyclotron-based solutions. The first design studies of the sector magnet of the main cyclotron show that the beam dynamics is acceptable with the obtained magnetic field. Due to its relatively compact size (outer diameter of 12 m) the complex can be an alternative to synchrotrons. Design study of the main cyclotron is described here.

THPSC013	The Nonsymmetrical Variant of the Nonferromagnetic Extraction Kicker Magnet of the NICA Booster	kicker, extraction, booster, acceleration	566
	V. Aleksandrov, A.A. Fateev, A. Tuzikov JINR, Dubna, Moscow Region, Russia
	Development and creation of the NICA acceleration complex are continued at JINR (Dubna). One of the main facilities of the complex is the Booster in which preliminary acceleration and cooling of an ion beam is performed. Further acceleration is fulfilled in the circular accelerator NUCLOTRON. The beam transfer from the Booster into the NUCLOTRON is provided by means of the fast extraction system and one of its central elements is the kicker magnet. For the beam deflecting into the extraction septum-magnet it is supposed to use the nonferrous kicker magnet consisting of two couples of conductors. Recent changes made in configuration of the Booster extraction section demand decrease of the kicker magnet length that leads to change of the beam extraction scheme. This report is devoted to the choice of the alternative design of the magnet (the nonsymmetrical variant).

	Yu. A. Rogovsky, E.A. Bekhtenev, M.I. Bryzgunov, O.I. Meshkov BINP SB RAS, Novosibirsk, Russia O. Chorniy GSI, Darmstadt, Germany
	The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.

New data on the development and experimental investigation of the RF accelerator based on the 9-cavities parallel-coupled accelerating structure that is equipped with a high-frequency grid-controlled electron gun are presented. Accelerating structure, injection system and focusing system are improved. Previously observed second emission resonant discharge - multipactor is suppressed by increasing the field amplitude in the structure first cavity and using the protector. The parameters of the accelerated beam close to the design ones, i.e. electron energy up to 8 MeV, capture to the acceleration mode up to 100%, were received. Capture is provided by the RF electron focusing of the microwave field structure with usage of the magnetic focusing system based on permanent magnets and RF grid control in the electron gun.

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.

Designs of systems of ion beam transfer from the linear accelerator HILAC into the Booster of the NICA accelerator complex (JINR, Dubna) including the transport beam line HILAC-Booster and the beam injection system of the Booster are considered in the report. The proposed systems provide multivariant injection for accumulation of beams in the Booster with required intensity. Special attention is paid to various aspects of beam dynamics during its transfer. Main methods of beam injection into the Booster are described. These are single-turn, multiturn and multiple injection ones. Results of beam dynamics simulations are presented. Status of technical design and manufacturing of the systems' equipment is also highlighted.

Since 1997, different variants of bunching systems have been used at the axial injections of FLNR cyclotrons to increase ions capture into acceleration efficiency. Combination of two single gap Sine and Line bunchers are used at the axial injections of U400 and DC110 cyclotrons. Since 2015, a single gap double RF harmonic buncher has been installed into the upper part of the U400M injection in addition to the lower sine buncher, the experimental results will be presented. For the HV axial injection of the new DC280 cyclotron, two variants of polyharmonic bunchers will be used: a multigap buncher and a single gap one.

An accelerating complex for hadron therapy is proposed. Facility consists of two superconducting cyclotrons and is aimed to produce beams of 12C⁶⁺ ions with energy of 400 MeV/nucleon. Accelerator-injector is a compact 70 MeV/nucleon cyclotron. Main machine is separated sector cyclotron consisting of six magnets. Basic features of the main cyclotron are high magnetic field, compact size, and feasible design of a magnetic system. The advantages of the dual cyclotron design are typical of cyclotron-based solutions. The first design studies of the sector magnet of the main cyclotron show that the beam dynamics is acceptable with the obtained magnetic field. Due to its relatively compact size (outer diameter of 12 m) the complex can be an alternative to synchrotrons. Design study of the main cyclotron is described here.

Development and creation of the NICA acceleration complex are continued at JINR (Dubna). One of the main facilities of the complex is the Booster in which preliminary acceleration and cooling of an ion beam is performed. Further acceleration is fulfilled in the circular accelerator NUCLOTRON. The beam transfer from the Booster into the NUCLOTRON is provided by means of the fast extraction system and one of its central elements is the kicker magnet. For the beam deflecting into the extraction septum-magnet it is supposed to use the nonferrous kicker magnet consisting of two couples of conductors. Recent changes made in configuration of the Booster extraction section demand decrease of the kicker magnet length that leads to change of the beam extraction scheme. This report is devoted to the choice of the alternative design of the magnet (the nonsymmetrical variant).

The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.
