摘要：

Propagation and absorption of second harmonic electron cyclotron resonance microwaves are investigated in Heliotron E. A highly focused beam with good single pass absorption allows a centrally peaked high electron temperature profile to be obtained. It is experimentally confirmed that the linearly polarized beam should be launched at a proper angle to the sheared field line and cross the resonance layer at the magnetic axis to obtain the best plasma production in heliotron/torsatron devices. The effects of ECH on NBI plasmas are studied by using two ECH systems with different absorption and resonance conditions. The superposition of ECH pulses on NBI plasmas has shown that Delta T-i > 0 for ECH overlapping with a rather broad ECH power deposition profile but Delta T-i < 0 for a centrally focused deposition profile. A key to an explanation of these different observations is the balance between the gain from Delta T-e > 0 (and from Delta E-r > 0, possibly) and the loss from the particle 'pump-out' and the resultant flattening of the density profile, both of which are caused by the ECH overlapping.
