Abstract:

The interaction between ECW and HL-2A plasma has been simulated using TORAY. The effects of plasma and wave parameters on ECRH ray trace, power deposition and current drive has been investigated. According to the calculation, when the linear-averaged density is 3.0×10¹³cm^-3 and the central temperature is 1.19keV, the single-pass absorption efficiency is 99.29%, and the maximum current drive efficiency is 0.005×10²⁰A•W^-1•m^-2.

Key words: TORAY, Ray tracing, Power deposition

摘要：

采用TORAY代码对HL-2A装置ECRH系统在单零点偏滤器位形下的波与等离子体相互作用的情况进行了模拟计算，研究了等离子体和波参数对ECRH波迹和功率沉积以及电流驱动的影响。根据数值计算结果，HL-2A装置ECRH系统在等离子体线平均密度为3.0×10¹³cm^-3、中心电子温度为1.19keV的情况下，以O模作为入射波垂直入射时的单次吸收系数为99.3%，最大电流驱动效率为0.005×10²⁰A•W^-1•m^-2。
