介绍了用硬X射线的针孔成像法测量简单磁镜装置MM-2中ECR等离子体特性的方法及结果。这种非破坏性的成像法,直观显示了热电子等离子体的空间分布,一次放电即可成一帧清晰的像。大量实验照片给出了发射强度随放电参数的变化关系。
The method and result of measuring the ECR plasma characteristics in MM-2 with hard X-ray pinhole imaging are introduced. This non-destructive imaging method visually shows the spatial distribution of hot electron plasma, a discharge can be a clear image. A large number of experimental photographs given the emission intensity changes with the discharge parameters.
