THE EFFECT OF ION CYCLOTRON RESONANCE HEATING ON LOWER HYBRID CURRENT DRIVE IN TOKAMAK PLASMA
离子迴旋共振加热对低杂波电流驱动的影响

A possible process occurring when ICRF wave for second harmonic heating of deuterium and LH wave for current drive are launched simultaneously into a D-T plasma in tokamak reactor is studied. The particle absorption of LH wave is calculated using linear theory. In combination with ICRH the LH-current drive efficiency is reduced. It decreases with increasing ICRF power due to the competing absorption of LH power by energetic D+. The absorption of LH wave by the energetic deuterium can be lowered by raising the LH wave frequency.
