Lower hybrid current drive experiments were carried out in the density range 1.0 x 10/sup 13/ less than or equal to anti n(cm/sup -3/) less than or equal to 1.0 x 10/sup 14/, at magnetic fields 6.0 less than or equal to B(T) less than or equal to 10. Using one 16 waveguide array, plasma currents of 150 to 200 kA have been driven by rf powers up to 600 kW for times greater than 100 msec at anti n/sub e/ up to 5 x 10/sup 13/ cm/sup -3/. With two arrays at anti n/sub e/ approx. = 4.3 x 10/sup 13/ cm/sup -3/ at B/sub T/ = 10 T, plasma currents of 160 kA have been maintained by the rf power for 300 msec with zero loop voltage and constant internal inductance.
