The cathode control circuit design of auto-gating power supply for low-light-level image intensifier

The image intensifier is special auto-gating power supply is an important component of the LLL image intensifier. It is the image intensifier tubes provide cathode, micro channel plate (MCP), anode the required voltage. It can realize automatic brightness control and image intensifier cathode protection function. The purpose of this paper is to design a cathode pulse control circuit which can protect the gating mode of auto-gating power supply and combining the independent cathode gating technology.
