三通道门控分幅相机及其触发晃动测量
|
摘要
研制了三通道微通道板(MCP)门控X射线分幅相机,其MCP微带阴极宽度为8 mm,相邻两阴极间隔为2.8mm,由幅值为-1.9kV和宽度为210ps的门控脉冲进行驱动。采用光纤传光束法测量了相机的触发晃动。实验结果表明,相机的触发晃动约为94ps,与高速示波器测得的90ps基本一致。此外,测得相机的时间分辨率约为100ps。
A microchannel plate(MCP)gated X-ray framing camera with three channels is developed,in which the width of the MCP microstrip line cathode is 8 mm and the gap between two neighboring photocathodes is 2.8 mm.The photocathode is driven by the gating pulse with the width of 210 ps and the amplitude of-1.9 kV.The trigger jitter of this camera is measured by the fiber bunch method.The experimental results show that the measured trigger jitter is about 94 ps,which is basically consistent with 90 ps by a high-speed oscilloscope.In addition,the measured temporal resolution of this camera is about 100 ps.
