The numerical design of the system includes calculation of the electrostatic field in the device, trajectories of electrons emitted from a photocathode, and determination of the modulation-transfer-function (MTF) which gives the objective estimation for the image quality. Results of the numerical experiments are shown, and the EOS with optimized characteristics is developed. It provides the nearly flat image surface, determines the position of the surface of the best focus, minimizes the image distortion and reduces a noise factor of the MCP.
