	The Nuclotron-based Ion Collider fAcility (NICA) is un-der construction in JINR. The NICA goals are providing of colliding beams for studies of hot and dense strongly interacting baryonic matter and spin physics. The NICA complex injection facility consists of four accelerators: Alvarez-type linac LU-20 of light ions up to 5 MeV/u; heavy ion linac HILAC with RFQ and IH DTL sections at energy 3.2 MeV/u; superconducting Booster synchrotron at energy up 578 MeV/u; superconducting synchrotron Nuclotron at gold ion energy 3.85 GeV/u. In the nearest future the old LU-20 will be substituted by a new light ion linac for acceleration of 2<A/z<3 ions up to 7 MeV/u with additional two acceleration sections for protons, first IH section for 13 MeV and the second one - superconducting for 20 MeV. The status of NICA injec-tion facility is under discussion.

MOPSA11	Room Temperature Folding Segment for a Transfer of Multiple Charge States Uranium Ions Between Sections of Linac-100	linac, simulation, electron, emittance	153
	V.S. Dyubkov MEPhI, Moscow, Russia
	Beam dynamics simulations results of multiple charge states uranium ions (238U⁵⁹⁺,60+,61+) in a transfer line between two LINAC-100 superconducting sections of DERICA project (JINR, Dubna, Russia) are presented. Transfer line is an advanced magnetic optical system and provides beams bending on 180 degrees. Transfer line options are proposed. Parameters of its optic element are chosen so that dispersion function has zero value at the start and end of the channel for transporting the 50 MeV/nucleon ion beams.

TUPSB48	Optimization of the Geometric Characteristics of the Laser Beam in a Multi-Pass Scheme of Nonlinear Amplification of the Master Oscillator Illumination	laser, plasma, ion-source, experiment	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.
