	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.

	Analysis of gas loads for the vacuum system chambers of the 6GeV synchrotron radiation (SR) source are carried out. The main source of gas loads is the photostimulated desorption induced by SR. 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.

WEPSC10	Optimization of Accelerators Vacuum Structures Pumping	361
	S.M. Polozov, A.S. Panishev, V.L. Shatokhin MEPhI, Moscow, Russia
	The pumping features for the complex parts of the accelerator vacuum system are modeled to growth the efficiency of vacuum pumping. The vacuum system of a 7.5 MeV/nucleon proton and light ion (A/Z<3.2) accelerator-injector was considered. The Monte Carlo method is suitable for molecular flow modeling in high vacuum. The Molflow+ program was used for this aim. The pressure distribution simulation over the RFQ, IH resonators chambers volume, connecting vacuum pipes and extended vacuum tracts is carried out. The influence of parameters of individual structural elements changes was investigated to define the vacuum conditions inside the accelerators vacuum chambers. The vacuum system configuration and parameters are selected basing on these results to obtain the required vacuum level.
