| 英文摘要 | pulsar navigation is a promising new technique for space exploration because of its autonomous and deep space capability. since the baseline of pulsar navigation approach is to observe the x rays (0.2∼20kev) emitted from pulsars, a compact high temporal resolution x-ray detector is needed. in this paper an micro-channel plate(mcp) photon counting detector sensitive to x-rays is proposed. the detection system consists of a csi photocathode, a 50mm diameter micro-channel plate (mcp) stack, a collection anode, a preamplifier, a constant fraction discriminator(cfd) and data acquisition(daq). the incident x-rays photons are absorbed by csi and converted to photoelectrons, the electrons are multiplied by mcp and collected by the anode. anode output signal is a fast pulse which need to be amplified by preamplifier and then fed to cfd circuit and daq for a precise timing. the total temporal resolution(δt) of the entire detection system could be determined by δtd, the intrinsic temporal resolution of cathode-mcp-anode, and δte the resolution of electronic system including preamplifier and cfd. the resolution of the detection system is tested to be 18.4ns in experiment. |
