MOPSA05	Beam Dynamics in ITEP Heavy Ion Linac
	G. Kropachev JINR/FLNR, Moscow region, Russia T. Kulevoy, A. Sitnikov ITEP, Moscow, Russia
	The pulse heavy ion linac accelerating ions with mass-to-charge ratio (A/Z) in the range 4 - 8 to energy 4 MeV per nucleon with a current of 10 mA is under development at ITEP. The linac including an RFQ section and two DTL sections (DTL1 and DTL2) operating at multiple frequencies is proposed. Each DTL section has a modular structure and consists of separated individually phased quarter-wave coaxial resonators (DTL1) and IH ones (DTL2) with focusing magnetic quadrupoles located between the cavities. This DTL structure provides linac compactness and enables its tuning and commissioning "cavity-by-cavity". A 6D-beam matching is carried out between all sections of the accelerator. The results of numerical simulation for particle dynamics are presented.

	The 4th generation light source, the Ultimate Source of Synchrotron Radiation (USSR) is under design, to be built in Moscow region (Russia). It will be a 6 GeV and about 1100 m circumference storage ring synchrotron. Baseline lattice of the USSR for now is a scaled version of the ESRF-EBS Hybrid Multi-Bend Achromat (HMBA) lattice that was successfully commissioned in 2020. Its natural horizontal electron beam emittance is about 70 pm·rad. Further reduction of beam emittance can be achieved with the use of reverse bending magnets. The evolution of the envisaged lattices for the USSR storage ring, including options with reverse bends will be presented.

TUPSB48	Optimization of the Geometric Characteristics of the Laser Beam in a Multi-Pass Scheme of Nonlinear Amplification of the Master Oscillator Illumination	327
	Yu.A. Satov, A. Balabaev, I.A. Khrisanov, T. Kulevoy, A.A. Losev, A. Shumshurov, A.A. Vasilyev ITEP, Moscow, Russia
	The paper presents the results of numerical simulation of the CO₂ MOPA laser scheme which is designed to generate powerful short radiation pulses in the ion source circuit. It is based on the nonlinear nature of the amplification of the master-oscillator pulse radiation, the front of which is formed by a nonlinear absorber. The paper considers the influence of the geometric parameters of the entrance beam in a four-pass amplification scheme. It is shown that for a fixed value of the small signal gain the maximum amplification effect is achieved with a certain formation of the spatial characteristics of the laser beam at the input to the amplifier. So some central uniform part of MO beam which has a Gaussian spatial profile is used in the telescopic amplifier. In this case, despite significant aperture losses, the maximum energy at the output of the amplifier is achieved with optimizing the beam diameter.

TUPSB49	Compact Ion Source for 3He²⁺ Beam
	D.N. Selesnev, A.V. Kozlov, T. Kulevoy, V.G. Kuzmichev, K.E. Prianishnikov, A. Zarubin ITEP, Moscow, Russia K.E. Prianishnikov MEPhI, Moscow, Russia
	Simulation experiments on irradiation with heavy-ion beams of structural steels are in demand as an express analysis of the steels radiation resistance. At the NRC "Kurchatov Institute" - ITEP the beam irradiation experiments are being conducted at the HIPr heavy-ion accelerator. It is essential to include helium and hydrogen beams for the proper simulation of radiation driven mechanisms of swelling and void formation. The 3He²⁺ ions enable both the low electrostatic acceleration for ion implantation in the region of interest and full separation from molecular hydrogen ions presented in the beam from ion source. The compact electron-cyclotron resonance ion source for 3He²⁺ ion beam generation was developed in ITEP - NRC "Kurchatov institute". The ion source design and beam parameters are presented and discussed.
