Description: ICRF experiments on ATF at the 100-kW level are planned for the current 1989 operating period. These plans include the 2..omega../sub cH/ regime at f/sub RF/ = 28.88 MHz, D(H) at 14.44 MHz, and /sup 4/He(/sup 3/He) and D(/sup 3/He) at 9.63 MHz. ECH target plasmas have n/sub eO/ /approx lt/ 0.15 /times/ 10/sup 20/ m/sup /minus/3/ and B = 0.95 T. The density and temperature profiles obtained are broader than those from 1988, owing to recent field error corrections. The values used for target-plasma parameters in the calculations were taken from initial 1989 ATF data. Loading and absorption calculations have been performed using the 3D RF heating code ORION with a helically symmetric equilibrium, and Fokker-Planck calculations were performed using the steady-state code RFTRANS with two velocity dimensions and one spatial dimension. 6 refs., 3 figs.
