Billen, J. H.

Two sources of negative ions are described. An rf source produces up to 14 ..mu..A beams of He/sup -/ by charge exchange in Rb vapor. The other Source of Negative Ions by Cesium Sputtering (SNICS) produces a wide variety of negative ion beams in the ..mu..A range. Two important features of SNICS are its simple, compact construction and its very good beam emittance (2 to 4 ..pi..mm mrad MeV/sup 1/). Both sources have lifetimes >200 hours and they are used extensively on the Wisconsin EN tandem.
