The long-term objective of the BNL Neutral Beam Development Group is to design and test a neutral beam system, using negative ion sources with a high beam current density. The principal elements of such a system are: a source of negative ions, beam extraction and transport system, accelerator, neutralizer, and the system for the removal and dumping (or energy recovery) of the remaining charged components of the beam. In the past year, a transition has been made from high current density, but pulsed, negative ion sources to sources designed to operate steady state. Two variants of the basic magnetron source geometry are being studied: the standard one with the discharge established in the interelectrode gap and the other with plasma injection from a hollow cathode discharge (HCD). Both sources have so far operated with steady state discharges.
