Negative Ion Beam Sources
Source of Negative Ions by Cesium Sputtering - SNICS II
The SNICS II is the most versatile negative ion source presently available. This sputter cathode source, shown at left with the extractor/lens assembly, produces ion beams for all elements which form a stable negative ion. More than 80 SNICS II ion sources are in use on Pelletron® accelerators and other tandem accelerators throughout the world. Its unique design and metal/ceramic construction with no organic seals in the main housing of the source has produced a reliable system with superior performance for all negative ions across the periodic table.
NEC maintains an ongoing research program to continuously improve the performance of the SNICS II source and to develop new ion beams. Cathodes for these ion beams are available from NEC. In addition, NEC maintains an active ion source test bench facility to develop new ion beams on request.
