Auxiliary heating results from PDX and PLT

Auxiliary heating experiments are continuing on both PLT and PDX. PLT has increased the available ICRF power delivered to the plasma to 3 MW for the 42 MHz system and to 1.6 MW for the 25 MHz system. Deuteron and electron heating are observed in the minority 3 He (T d approximately 2.8 keV, T e approximately 2.2 keV) and H (T d approximately 2 keV, T e approximately 2.2 keV) heating regimes. In addition, ion heating has been observed in the second harmonic regime (T eff =2/3 (E h )=3.3 keV). Recent auxiliary heating of low q(
