This paper discusses the experimental results obtained from the various components developed
for a 1.7 MW neutral beam injector (NBI). Several technologies related to fabrication of back
plate, extractor grids, high-current filament feedthru’s, heat-transfer elements, ceramic insulators,
cryopumps, rectangular vessels and power supplies have been developed in collaboration with the
Indian industry. Control experiments on the prototype plasma box are described.
