Abstract
National Electrostatics Corporation has designed, built and tested a high current negative ion helium injector for use with tandem electrostatic accelerators adapted from the high current NEC H− injector. This injector system consists of a NEC Toroidal volume ion source (TORVIS) followed by a rubidium vapor charge exchange cell. The observed He− beam current after mass analysis was routinely 20μA with a maximum beam current of 32μA. This compares to the 2–4μA from a standard RF charge exchange He− injector.
