Abstract

The low gain of single micro-channel plate (MCP) detector system has a lot of restrictions. So the dual MCP system is widely applied in many fields. Many experiments showed the gain was proportional to initial electron energy in single MCP system. If we improve the initial energy that collide with the second MCP in dual MCP system, it may have beneficial influence on the system gain. In order to check these hypothesis, we use the “Secondary Electric Field Acceleration” cascade structure in experiments. The results show the correctness through the comparison test with conventional 'V' type cascade structure. In this paper, we describe the different between these two structure and discuss the influence factors in their system gain. It gives a reference in the cascade system that with high gain and it also takes a great significance on the weak-light-detection field.
