  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.

  Particle sources might be considered as an incredibly significant part of the accelerator system. Nowadays high-energy acceleration requires the types of ion sources implemented to produce beams of ions and protons of high energy and intensity. The current study is aimed to con-sider the design of the magnetic system of ECRIS with the operating frequency of 2.45 GHz for producing pro-tons and double-charged helium ions. The numerical simulation of the magnetic system was made by the Finite Element Method. The adjustment of the axial distribution of the magnetic field inside the plasma chamber is realized by shifting the ring magnets. Additional tuning of the axial magnetic field is presented by solenoids introduced for providing the required Binj and Bext adjustment as well as the Bmin control on the axis. For the simplification of the structure the alternating design of the ring magnets with trapezoidal components was considered. Furthermore, the magnetic system allows operating in both single-charged and multiply charged ions generation modes, thus the microwave source mode and the ECR mode are realizable for this configuration. Therefore, the study enables a better understanding of the feasibility of the ECRIS magnetic system with variable characteristics.
