Design of an EBIS for RHIC
2003
An Electron Beam Ion Source (EBIS) can be used to produce beams of high charge state heavy ions, and is an excellent choice for injection into a synchrotron, since short pulses of high intensity can be produced for single-or few-turn injection into the ring. As a result of successful experiments on a test EBIS at BNL, we are now confident that an EBIS meeting RHIC requirements can be built. This EBIS would be part of a new linac-based preinjector which would serve as a modern alternative to the existing Tandem preinjectors, offering improvements in performance and operational simplicity. The BNL test EBIS, which is a 1/2 trap-length prototype of the RHIC EBIS, has produced > 10/sup 9/ ions per pulse of Au/sup 32+/, in 10-20 microsecond pulses, and has exceeded our design goals. Performance of the test EBIS is summarized and the design of the RHIC EBIS presented.
