ELECTRON POWER DEPOSITION PROFILE DURING ICRF HEATING ON JET
The first measurements of the electron power deposition profile for ICRF heating on JET are presented. In the two-ion regime (H or He**3 in D-H or D-He**3 plasmas), it is found that the power deposited directly to the electrons is strongly peaked within the volume limited by q = 1. Indeed, "giant" sawteeth have been induced by application of RF at megawatt power levels. The sawtooth amplitude and period appear dependent on both the location of the cyclotron resonance layer and k-" spectrum of the antenna.
