  By simulating the X-ray paths and the Chapman Model of a flat multi-channel
plate and a curved multi-channel plate in the MATLAB, the field of view, local
reflection efficiency, spherical aberration, point-spread function, collection
efficiency of incident X-ray and peak-to-background ratio on the focal plane of
the two devices were compared. At the same time, the advantages and
disadvantages of the flat multi-channel plate and the curved multi-channel
plate were compared.
