Lower hybrid current-drive experiments have been carried out on the PLT Tokamak. Steady currents up to 175 kA have been maintained for three seconds and 400 kA for 0.3 sec by the rf power alone. The principal current carrier appears to be a high energy (approx. 100 keV) electron tail, concentrated in the central 20 to 40 cm diameter core of the 80-cm PLT discharge. Effective current drive is observed only for anti n/sub e/ less than or equal to 8 x 10/sup 12/ cm/sup -3/. This limitation may be a wave propagation phenomenon and not a fundamental plasma physics effects.
