| 摘 要： | 研制了一种双微通道板（Microchannel Plate,MCP）双选通型软X射线分幅相机.该相机采用两块厚度为0.5 mm的MCP,近贴放置成“V”形结构,用两列高压脉冲依次选通两块级联的MCP,通过控制两列脉冲之间的延迟时间,利用微通道板的电子渡越时间效应和非线性增益的相互作用,以损失一部分电子为代价获得比单MCP（60 ps）选通相机更短的曝光时间,并且可以降低直穿X射线造成的背景光噪音. |

| Abstract: | A soft X-ray framing camera with two micro-channel plates was developed.It consists of two MCPs in V-configuration,of which the thickness is 0.5 mm respectively.Two columns of high voltage pulse are used in gating two cascade MCPs.By controlling the pulse delay-time and using the interaction between time effect of electron transition through micro-channel and nonlinear gain,35 ps exposure time is obtained which is shorter than a single MCP camera′s by losing a number of electrons. And the background noise caused by straight X-ray can be reduced. |
