Study of a four hole ECR ion source for a HIF injector

Abstract We have designed an ECR ion source which extracts four equal beams from one chamber as a study of an ion source for an accelerator that has several RFQ channels in one accelerating cavity for a heavy ion, HIF accelerator. Solenoid coils for the mirror magnetic field were designed using the magnetic field calculation program OPERA. Extraction electrodes were designed by using particle orbital calculation program FUGUN. Based on the above, we designed and manufactured four hole ECR ion source.
