摘要
利用电流丝模型编写的电流丝编码和采集到的18个磁探针测量数据、等离子体电流和极向场线圈电流的数据做了重建HL 2A等离子体边界的研究。计算结果表明,电流丝编码能够正确地识别等离子体的边界、偏滤器位形和X点的位置。计算获得的偏滤器内外靶板上打击点出现和消失的时间与布置在偏滤器靶板上静电探针测量到的信号很好地符合。在Pentium4的PC个人计算机上(CPU为2.4GHz,800MHz总线)计算每一个时刻的等离子体边界时间小于1ms。
To reconstruct the HL-2A plasma boundary, current filaments (CF) code with the filament current model is written. Computed results based on the external magnetic measurements show that the CF code can accurately identify the limiter plasma, and the diverted plasma with its X point position. The time of the appearance and disappearance of the strike point at the target is in agreement with the signals measured by the static electric probes. Using an ordinary PC (Pentium 2.4 GHz, 800 MHz data bus), the calculation time of the plasma parameters is less than 1 ms.
