Abstract

This paper describes the preliminary design and performances of a new developed photon counting imaging detector for Chinese ChangE-2 EUV explorer mission. The detector consists of microchannel plate (MCP) stacks and wedge and strip anode and corresponding data read out electronics. The experimental results shows that the new developed detector has a spatial resolution of about 75μm, image distortions are small and dark noise count rate less than 0.4 counts cm^-2s^-1. The pulse height distribution vs MCP operating voltages and the flat field performances are also discussed.
