摘要
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 hydrogen pellet injection experiments on the HL 1M tokamak, from multi channel H α signals detected with a 20 channel PIN detector array located on the top port at the poloidal cross section where the pellet injecting port is, the H α radiation intensity profile is obtained with Abel inversion and the pellet location varied with time, namely the pellet penetration, is found . The scaling relationship of the pellet penetration depth with electron temperature and electron density is analyzed. And the relative variation for the whole particle confinement time is also analyzed according to the HCN multi channel signals of electron density and the signals got from a 22 channel PIN detector array on the horizontal port at an angle 115 o from the pellet injecting port.
