Two-dimensional imaging x-ray spectrometer using channel-plate collimator

Abstract
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.
