Study of ECRIS for highly charged ion production: HiECR MK3

摘要

The former HiECR had good performances in 6 and 10 [GHz] operations, while in the case of 14 [GHz] operation, the intensity of highly-charged heavy ions was very low [1,2,3]. It seemed that the result was due to the narrow gap(3[mm] or less) between the surface of ECR zone and that of the chamber wall.rnHiECR MK3 has been designed to produce strong axial mirror field and radial hexapolar field enough to 14 [GHz] operation.rnThe HiECR MK3 was constructed and operated for the first time.
