摘要
研制了应用于平焦场光栅谱仪系统的宽微带X射线分幅相机,微通道板(MCP)微带阴极的宽度为20 mm,由四路选通脉冲同时驱动。分幅相机采用模块化设计,由气室、MCP变像管、电控系统、光学CCD记录系统和内嵌式计算机组成,内嵌PC104模块实现相机的远程控制。对相机进行联调实验,测得该相机的时间分辨率为71 ps,空间分辨率为20 lp/mm,垂直于选通脉冲传播方向的微带均匀性为1.51,平行于选通脉冲传播方向的微带均匀性为5.11。
Abstract
An X-ray framing camera with wide microstrip line is described. It is designed for the flat field grating spectrograph. The microstrip line cathode deposited on the microchannel plate (MCP) with width of 20 mm is driven by four gating electrical pulses. The camera with modular design is made up of five basic components: the airbox, the MCP imager, the electric control system, the CCD camera system and the embedded computer. The camera is remote controlled by the embedded computer PC104. The camera is tested and the results show that the exposure time of the camera is 71 ps, the spatial resolution is 20 lp/mm, the gain uniformity of the microstrip line photocathode transverse to the pulse propagation direction is 1.51, and the gain uniformity along the pulse propagation direction is 5.11.
