	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.

	The new linac for light ion beam injection is under development at MEPhI. Such linac was proposed for acceleration of 7.5 MeV/u ion beam with A/Z=1-3 and current up to 5 mA for proton and 0.4 pmA for light ions. The linac general layout will include two types of ion sources: ECR ion source for proton anf He ions and laser ion source for ions form Li to O. Following the LEBT ions will be bunched and accelerated to the final energy using RFQ section and 14 IH cavities. These IH-cavities will be identical (divided into two groups) and independently phased. All cavities will operate on 81 MHz. Results of the beam dynamics simulations and the cavities design will presented in the report.

	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.

WEPSC07	Medium Energy Ions Transport Channel for a Pulsed Linear Accelerator	355
	V.S. Dyubkov MEPhI, Moscow, Russia
	For a transportation and matching proton and light ion beams (the maximal value A/Z is about 3.2) between RFQ and groups of IH-cavities it is suggested medium energy ions transfer line. That line should provide 100% beam transmission under negligible beam envelope increase and small longitudinal beam size growth during particle transport. MEBT consists of two parts. One of them provides ion transfer with energy 820 keV/u and the second one provides ion transfer with energy 2.46 MeV/u.

The influence of storage ring lattice, geometric dimensions and beam parameters on the vacuum conditions in SR-source prototype chambers is studied. The geometric model of the storage ring chamber designed for simulation is considered. The simulation of the radiation flux parameters generated by the charged particles passing through the section of the vacuum chamber has been performed. The technique of calculating the parameters of SR and photostimulated desorption by means of Synrad+ and Molflow+ codes is applied.
