This ion source is a 3rd generation ECR machine optimized for the operation at 28 GHz. As a second superconducting ECR ion source developed at IMP with the identical coldmass design as SECRAL ion source, which has the sextupole coils external to the axial solenoids, the magnet performance is more robust according the training test. After a short time beam test at 18 GHz, SECRAL II has been commissioned at 28 GHz, and some preliminary results have been achieved with high charge state ion beam production. This paper will present the magnet design and test results. The first beam at 28 GHz will also be given.
