提出了一种用于 X 射线脉冲星导航的 X 射线光子计数探测器原型。该探测器由CsI光电阴极、微通道板(MCP)电子倍增器、收集阳极和电子读数器组成。对灵敏度、时间分辨率和死区时间进行了测试，结果表明探测器在5 keV下的灵敏度为5.2 x 10(3) A/W，时间分辨率为1.1 ns，死区时间为100 ns。
A prototype of x-ray photon counting detector is proposed for x-ray pulsar navigation. The detector consists of CsI photocathode, micro-channel plate (MCP) electron multiplier, collect anode and electronic readout. The sensitivity, the temporal resolution, and the dead time are tested, and the results show that the sensitivity of the detector is 5.2 x 10(3) A/W at 5 keV, the temporal resolution is 1.1 ns, and dead time is 100 ns.
