Abstract

The superconducting tokamak HT-7U, which is used to research fusion technology has been under design by the Institute of Plasma Physics since 1998 and will be set up before 2003. HT-7U provides increased capability and will replace the former HT-7 tokamak in 2003. The 1.2 MW, 2.45 GHz HT-7U LHCD (lower hybrid current drive) system is a noninduction device which efficiently heats the plasma and drives the plasma current. The particular design of the 2.8 MW/-35 kV high-voltage DC power supply (HVPS) for the future HT-7U fusion systems has been completed and has successfully supplied the LHCD klystrons on HT-7 demonstrating reliability and feasibility.
