Description
This paper reports on a teststand of the negative ion based NBI for the LHD which is under construction, which has capabilities of the neutral beam 2.5 MW at the beam energy of 125 keV(H0)/250 keV(D0) with the pulse duration of 10 sec. Components for the R and D are as follows: a large and high current negative ion source which is immersed in the vacuum and composed of a compact modular ion source, the beam dump to remove the high heat flux up to 1.6 kW/cm2, high pumping speed (450 m3/s) cryopump, 250 kV power supply system using GTO, and the controller system to vary the beam energy within 0.5 sec. Testing will commence in the spring of 1992 at Toki new site
