Experimental investigation on electron cyclotron absorption at down-shifted frequency in the PLT tokamak

The absorption of 60 GHz electron cyclotron waves, with the extraordinary mode and an oblique angle of propagation, has been investigated in the PLT tokamak in the regime of down-shifted frequency. The production of energetic electrons, with energies of up to 300 to 400 keV, peaks at values of the toroidal field (≈29 kG) for which the wave frequency is significantly smaller than the electron cyclotron frequency in the whole plasma region. The observations are consistent with the predictions of the relativistic theory of electron cyclotron damping at down-shifted frequency. Existing RF sources make this process a viable method for assisting the current ramp-up and for heating the plasma of present large tokamaks.

60 GHzの電子サイクロトロン波の吸収が、異常モードおよび斜め伝播角度において、PLTトカマクで周波数下方シフト領域について調査された。高エネルギー電子の生成は、300〜400 keVまでのエネルギーで、トロイダル磁場(約29 kG)の値においてピークに達し、その際、波の周波数はプラズマ全域で電子サイクロトロン周波数よりも有意に小さくなる。これらの観測結果は、周波数下方シフトにおける相対論的電子サイクロトロン減衰の理論的予測と一致する。既存のRF源は、このプロセスを現在の大型トカマクにおける電流ランプアップ支援およびプラズマ加熱の実現可能な方法として提供する。
