  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 results of numerical simulations of multipacting discharge in accelerating Interdigital H-type (IH) cavities are presented in this paper. Optimal design parameters were selected to reduce the number of multipactor electrons. The localization of multipactor trajectories in the short 5-gap 80 MHz IH cavities at various levels of accelerating voltage is considered.
