Abstract

Steady-state ion cyclotron range of frequency (ICRF) heating technologies were developed to heat plasma for >30 min in a large helical device (LHD). Steady-state-operation tests of high voltages up to 40 kV0p for >30 min were carried out on radio-frequency vacuum feedthroughs and a coaxial transmission line in a test set. The performance of the feedthroughs and transmission line exceeded the specifications for steady-state heating in the LHD.
