At Brookhaven National Laboratory, an Electron Beam Ion Source (EBIS) is operational and has produced charge states such as N{sup 7+}, Ar{sup 16+}, and Xe{sup 26+} using neutral gas injection. Ions such as Na{sup 7+} and Tl{sup 41+} have been produced using external ion injection. The BNL EBIS effort is directed at reaching intensities of interest to RHIC, approximately 3{times}10{sup 9} particles/pulse which will require EBIS electron beams on the order of 10 A. Pulsed electron beams up to 1.14 A have been produced using a 3 mm LaB{sub 6} cathode. Ion yields corresponding to 50{percent} of the maximum trap capacity for electron beams up to 0.5 A have been obtained. The goal for the TestEBIS is to produce a uranium ion charge state distribution peaked at U{sup 45+} with 50{percent} of the trap capacity for a 1 A electron beam.
