摘要
在一些HL-1托卡马克的低杂波电流驱动(LHCD)实验中,驱动效率对低杂波注入功率和等离子体电子密度等参数的依赖关系很分散。分析表明,其可能原因是驱动电流的计算不够精确,携带电流的快电子的相当部分逃离等离子体后损失到孔栏或真空室壁上以及放电的重复性差等。
Reported dependences of the HL 1 lower hybrid current drive efficiency on injected RF power and plasma electron density are very diversified. It seems to be caused by errors in RF current estimates, the irregular fast electron loss to the limiter and vessel and poor repeatability of discharges. In this paper these questions are discussed in detail.
