Neutral beam injection research and development at Brookhaven National Laboratory, Lawrence Berkeley and Livermore Laboratories, and Oak Ridge National Laboratory is described. The ORNL Neutral Beam Development Program is concentrated on the development and application of tokamak neutral beam injection systems. Tokamak neutral beam development is being carried out for ORMAK, PLT, ORMAK-Upgrade, PDX and TFTR. Applications have been made to ORMAK and are being made to PLT. Basic research in support of the development program includes work in the areas of plasma sources, ion extraction and beam optics, cryopumping, beam stops and megawatt electrical power systems. The LBL/LLL Neutral Beam Development Program can be divided into two areas: (1) development based on positive-ion acceleration and neutralization, primarily for near-term applications on the 2X, BB, MX, and TFTR confinement experiments, and (2) a higher-efficiency-injector program based on acceleration and neutralization of negative ions, which may be required for fusion reactors and reactor-like experiments. The objective of the BNL Neutral Beam Program is to develop a 150 keV multiampere (equivalent) neutral injector with essential support systems based on long pulse, multiampere sources of negative hydrogen and deuterium ions, close coupled acceleration to the required energy and on neutralization of high energy negative ions in a gas or plasma jet. High speed cryogenic and molecular sieve pumps are being developed as part of the program.
