Abstract

It is shown in this paper that if two microchannel plates are used in chevron configuration and are gated one by one by ultrashort electric pulses, the exposure time can be reduced considerably compare to that of one MCP due to the superposition of the gain narrowing effects of the two stages gating. Another advantage of this method is that the signal to noise ratio can be improved because of the increase of gain and reduction of hard X-ray induced background.
