摘要
在HL-2A单零偏滤器条件下,对由弱场侧沿赤道平面垂直注入的电子回旋寻常波(O-模)的波迹和波的功率沉积剖面进行了分析计算。对近磁轴共振情形,需要确定一个有效的物理尺度以正确获得波功率沉积。单一波束的有效吸收层的厚度可以合理地作为这一物理尺度,从而获得统一的功率沉积公式。对比研究了磁轴偏离赤道面和位于赤道面情况下的波功率沉积剖面。
With the single-null divertor configuration on the HL-2A tokamak, the ray tracing and the wave power deposit for the ordinary electron cyclotron wave, perpendicularly injected from the weak field side, are analyzed. For on-axis resonance, it is necessary to determine a physical scale length to treat adequately the wave power deposit profile. The effective absorption layer of a single ray can be used as such physical scale length to obtain a formula for the wave power deposit. As examples, results of wave power deposit profiles for on-axis heating are reported for both cases of the magnetic axis locate on and depart from the equatorial plane.
