| 摘 要： | 基于高功率激光等离子体X射线辐射谱特性,设计和研制了一种大画幅高动态范围MCP选通型分幅相机. 单画幅宽度13mm,长度36mm,曝光时间0.5—5ns可调.与X射线CCD比较,系统在1.0—10keV的谱响应相对平整,无高能增强效应.利用高功率激光打靶实验进行了性能考核实验,结果表明,系统的信噪比明显好于X射线CCD系统,动态范围大于3×103. 系统已经在神光Ⅱ装置ICF物理实验中获得成功应用.

| Abstract: | High dynamic range and large format technique of micro-chanunel plate (MCP), gated framing camera is developed to diagnose high-power laser-plasma X-ray emission spectra. The single frame format is 13 mm×36 mm, and exposure time is adjustable from 0.5 ns to 5 ns. Its spectral response in 1.0—10 keV is more flat than that of X-ray charge-coupled device (CCD), and there exists no energetic enhancement effect. Performance evaluation has been conducted on high power laser devices, and the results show that the system has a high signal-to-noise ratio and the dynamic range is greater than 3 × 103. The system has been applied successfully to inertial confinement fusion (ICF) physics experiment. |
