摘要
微通道板(MCP)选通软X射线皮秒分幅相机(XPFC)的动态时间分辨率是其重要的性能指标之一.通过基于均匀设计分析法建立的MCP-XPFC的动态时间分辨率回归方程着重分析了选通电脉冲的宽度和幅值对MCP-XPFC的动态时间分辨率的交互影响.在选通电脉冲V1(t)(250ps,1200V)和V2(t)(170ps,1400V)的作用下,利用MCP-XPFC的选通理论模型、均匀分析法回归方程、以及飞秒激光系统分别对相机的动态时间分辨率进行了理论计算和实验测试,并对结果误差进行了分析.对于250ps的选通脉冲适合的电压范围约为800～1200V,而对于170ps的选通脉冲适合的电压范围为1100～1200V.
The soft X-ray picosecond framing camera based on the gated microchannel plate （MCP-XPFC） is a type of ultra-fast diagnostic tool that applied widely for ICF and plasma researches. By using the uniform design,a temporal-resolved regression equation of MCP-XPFC was presented. The analytic emphasis is the interaction of the gating electric pulse＇ s width and amplitude on the temporal resolution. The temporal resolution of camera was computed by the gating theoretic model and the regression equation respectively, and measured by femtosecond laser system on the base of two groups parameters, the gating electric pulses applied on the micro-strip lines of the MCP-XPFC with V1 （ t ） （250ps, 1200V ） and V2 （ t ） （ 170ps, 1400V ）. At last, the theoretic and experimental error was analyzed.The optimized voltage range are 800- 1200V for electric pulse of 250 ps and 1100- 1200V for electric pulse of 170ps.
