Progress on Test EBIS and the Design of an EBIS-Based RHIC Preinjector

Following the successful development of the Test EBIS at BNL [1-3], we now have a design for an EBIS-based heavy ion preinjector which would serve as an alternative to the Tandem Van de Graaffs in providing beams for RHIC and the NASA Space Radiation Laboratory. This baseline design includes an EBIS producing mA-level currents of heavy ions (ex. Au³²⁺) in ∼ 10-20 μs pulses, injecting into an RFQ which accelerates the beams to 300 keV/amu, followed by an IH linac accelerating to 2 MeV/amu. Some details of this design are presented, as well as recent experimental results on the Test EBIS.
