Intense Beam Ion Sources Development at Imp *

To satisfy the HIRFL (Heavy Ion Research Facility in Lanzhou) accelerators’ requirement and the needs of several other future accelerator facilities, many high beam intensity ion sources have been developed at IMP. The ion sources include intense high charge state ion beam ECR ion sources and high intensity proton beam ECR or microwave sources. This paper will review the high charge state ion sources developed at IMP, especially the recently built fully superconducting ECR ion source SECRAL, and the other classical ion sources and all permanent magnet ion sources will also be discussed. The latest performance of the recently built intense proton ion source which can operate continuously at more than 65emA beam (after LEBT) and 50kV source high voltage for more than 150 hours with very few HV spark intervals will be especially presented in this paper. Recent studies concerning the ion sources for HIAF project are also given.
