4. What's New at HRIBF - A New SNICS II (Source of Negative Ions by Cesium Sputtering) Ion Source to be Installed on the Stable Injector.
(M. Meigs)

A new SNICS II (Source of Negative Ions by Cesium Sputtering) ion source has been purchased from National Electrostatics Corporation (NEC) to be installed on the stable injector. The source has been delivered in February and will be installed in the next long tank opening. This source is the 90th single-cathode source that NEC has sold and they have 62 multi-cathode sources in use around the world. It is expected that the large user community will be a good resource when having problems or trying to develop beams. It is also expected that this source will provide higher beam currents than our present one. After the source has been installed, it will be the permanent stable ion beam source. Though we expect the SNICS II to be an improvement, there will be a learning curve to determine the exact parameters to optimize each beam.

A list of beams which will be available at the time of installation is presented below (all materials are of natural abundance unless specifically noted):

1,2H, Li, 10B, C, N, 16,17,18O,F, Mg, Al, Si, S, Cl, Ca, Ti, Fe, Ni, Cu, Ga, Ge, As, Se, Br, Zr, Mo, Ag, Sn, Te, I, Pt, and Au.

Contact Carl Gross if the beam you need is not on our list.
