在 HL - 1M装置氢弹丸注入实验中 ,利用位于弹丸注入口上面、同一极向截面上的窗口上布置的一个 2 0道 PIN探测器阵列所获得的多道 Hα辐射信号 ,借助于 Abel变换算法反演出 Hα辐射强度径向剖面随时间的演变 ,确定了弹丸在不同时刻在等离子体中所处的位置 ,即穿透深度。分析了穿透深度与等离子体温度和密度之间的定标关系。利用在离弹丸注入口 115o 的水平窗口上布置的 2 2道 PIN探测器获得的信号和多道 HCN等离子体电子密度测量信号估算了弹丸注入后整体粒子约束特性的相对变化。
In the HL - 1M device hydrogen projectile injection experiments, the multi - channel Hα radiation signals obtained by using a 20 PIN detector array located on the window of the same polar cross section above the shot inlet were analyzed by Abel transform algorithm The evolution of the radial profile of the Hα radiation intensity over time was inverted, and the location of the projectile in the plasma at different times, ie the penetration depth, was determined. The scaling relationship between penetration depth and plasma temperature and density was analyzed. The relative change in global particle confinement characteristics after bolus injection was estimated using signals obtained from 2 2-channel PIN detectors arranged on a horizontal window of shot injection port 115o and multichannel HCN plasma electron density measurement signals.
