Framing cameras based on the gated microchannel plate (MCP) are versatile diagnostic tools for fast Z-pinch and inertial confinement fusion experiments. In order to understand the temporal characteristic of the MCP used in such camera, the MCP is simulated using the Monte Carlo method. By simulating the electron cascade in the MCP, the relationship between the MCP temporal resolution and the ratio of its thickness to the channel diameter (L/D ratio) is obtained. The variation of the temporal resolution with the voltage applied on the MCP is also provided. The transit time and the transit time spread (TTS) simulations of the MCP are presented. The simulated results show that the transit time and TTS of the MCP are increased with L/D ratio increasing while the channel diameter of the MCP is 10 um.
