应用微通道板通道玻璃表面对大角入射的X射线吸收和小角入射的X射线全反射的特性,讨论适用于硬X射线和软X射线准直的两种类型微通道板,分析影响准直性能的因素。最后,对硬X射线微通道板准直器的辐射通量与通用准直器的进行比较。
The characteristics of X-ray absorption and small-angle X-ray total reflection of large-angle incident on the glass surface of microchannel plate were discussed. Two types of microchannel plates suitable for hard X-ray and soft X-ray collimation were discussed. the elements of. Finally, the radiation flux of the hard X-ray microchannel plate collimator is compared with that of the general collimator.
