Two‐dimensional imaging x‐ray spectrometer using channel‐plate collimator
暂无分享,去创建一个
A new method for two‐dimensional imaging x‐ray spectrometer is introduced. The optical system consists of a microchannel plate as a large‐aperture collimator and a flat Bragg‐type diffractor. This method can be applied to radiation covering from VUV to hard x ray. The feasibility has been demonstrated by using x rays of two different energies and a LiF crystal.
