摘要：
X-ray detector based on the gated microchannel plate (MCP) is a powerful diagnostic tool for laser-driven inertial confinement fusion and fast Z-pinch experiments. In order to understand the behavior of the MCP used in such detector, the X-ray detector is simulated using the Monte Carlo method. By simulating the electron cascade in the MCP, the relationship between the MCP gain and voltage is obtained. The time, position and energy of the electrons at the MCP output surface are calculated. The transit time distribution, the electron-channel wall collision number distribution and the time distribution of the electrons travel from the MCP to the phosphor screen are given. Spatial resolution simulations of the MCP-based detector are also presented.
