Abstract

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.
