在具有非零环电压的低杂波电流驱动(LHCD)等离子体中，快电子尾部可以作为逃逸的种子种群。研究发现，当快电子尾部延伸到电子逃逸的临界速度以上时，在低杂化(L H)波的存在下，逃逸会得到增强。在失控放电中，由于与无感电流驱动相关的电场下降，LH波可能会抑制失控电子。本文给出了逃逸电子在大范围LHCD等离子体中的行为。
In lower hybrid current drive (LHCD) plasmas with non-zero loop voltage, the fast electron tail can act as a seed population of runaways. The runaways are found to be enhanced in the presence of lower hybrid (LH) waves when the fast electron tail extends above the critical velocity for electrons to run away. In runaway discharges, the LH waves may suppress runaway electrons due to the drop in the electric field linked to the non-inductive current drive. In this paper, the behaviour of runaway electrons in an extensive range of LHCD plasmas is presented.
