Abstract
Microchannel plate (MCP) is a core part of the X-ray framing camera. Studying the dynamic characteristics of the MCP is critical to understanding the data obtained by the framing camera. The dynamic characteristics of the MCP with different dc bias voltage are simulated by using the Monte Carlo method. The relationship between the theoretical exposure time and the MCP bias voltage is obtained. A MCP gated X-ray framing camera is developed. The measured exposure time increase 9 ps while the MCP bias voltage is -300 V comparing to -200 V. The simulation and experimental results show that the exposure time and gain of the MCP are both increased while the negative bias voltage is increased.
