  • MC-SNICS Workshop, National Electrostatics Corp., Middleton, WI, USA
    NSF has funded AMS labs at University of California, Irvine, University of Arizona, and Woods Hole to work together with NEC on developments and improvements of the MC-SNICS source. A small ion source workshop was held at the NEC plant on Nov. 3-4, 2003 to discuss problem areas and to come up with an initial set of modifications that the three labs could try. Changes already implemented at other labs were also discussed, and there were also presentations on the high-intensity LLNL source and the new PRIME "rabbit" sample changer source.
