| 摘 要： | 本文描述用硬X射线针孔成象法测量简单磁镜装置中ECR等离子体辐射特性的方法及其结果。这种非破坏性的成象法,直接显示了热电子等离子体的空间分布,一次放电可成一帧清晰的象,且由此可得出二维的等发射强度线。大量结果表明电子环是非轴对称的,并非为一个整环,而是在微波注入口的对面有一个缺口。当微波功率改变时,环也在改变。

| Abstract: | The hard X - ray pinhole imaging method and its application in a simple mirror for measuring the radiation properties of ECR plasma are presented in this paper. This imaging method can directly display the spatial structure of the hot electron annulus without disturbing the plasma. Clear visual pictures of the electron annulus can be taken at suitable discharge conditions and a two dimensional contour of radiation intensity is deduced . Usually,the electron annuli with azimuthal asymmetry were observed,some with a gap at the ring. The azimuthal asymmetry of annulus is changed as we vary the microwave injection power. |
