BNL neutral-beam development group. Progress report FY 1982
Efforts were concentrated on the development of H/sup -//D/sup -/ sources capable of delivering about 1A of beam current, operating steady state at an energy of several tens of keV and having properties that would allow a scaling up to 10A and their use in a high energy neutral beam line. In the seventies we have developed negative ion sources of the plasms surface type with extracted current densities of several hundred mA/cm/sup 2/. Particularly successful was the development of the magnetron source, from which pulsed beam currents in excess of one ampere have been obtained and accelerated up to 120 kV. These magnetrons have become standard sources in high energy accelerator laboratories around the world and they are candidates for application in polarized H/sup -/ ion sources as well. Work on hollow cathode deuterium sources and neutraizers is reported.
