6. Update on
the New SNICS II (Source of Negative Ions by Cesium Sputtering) Ion Source
(M. Meigs, spokesperson)
The new SNICS II (Source of Negative Ions by Cesium Sputtering) ion source, purchased from National Electrostatics Corporation (NEC), was installed on the stable injector August 12, 2008. Experience is being gained by the operators to learn the SNICS personality. It does typically produce an abundance of beam when compared to the previous source. More difficult beams, which require gas feeds, will be possible when the gas cathode option is installed. A specific date for this installation has not been set.
Since its installation, the new SNICS II source has produced the following
beams: H, B, C, Ti, Ni, Ga, Ge, As, Br, Ag, In, Sn, Sb, and Te.
