Abstract

The X-ray spectrograph based on mica crystal (2d=19.9/spl Aring/) for spectrum analysis is described. The device construction (/spl theta/-2/spl theta/ scheme) is suited for radiation detectors: film, charge coupled device (CCD) and microchannel plate (MCP). X-ray film is used for spectrum measurements in the working range of the device (3/spl Aring/-18/spl Aring/). The device working range is measured by CCD. The CCD length is 3 cm. It correspond to the /spl Delta//spl lambda/=4/spl Aring/ range of the X-ray spectrum. An analog CCD signal is transformed to digital form and is sent to an IBM PC. The computer software has codes for plasma parameter determination (T/sub e/,n/sub e/). The CCD characteristics in the X-ray region have been initially researched. Some of these results are given. There are two time resolved detectors for plasma dynamic measurements. The construction of these detectors is based on microchannel plates. The X-ray range of the MCP detector is /spl Delta//spl lambda/=0.1/spl Aring/. Some results of this device application at the pulsed power facilities ANGARA-5 and GAEL are given.

多功能x射线摄谱仪

介绍了一种基于云母晶体(2d=19.9/spl Aring/)的x射线光谱仪，用于光谱分析。器件结构(/spl θ /-2/spl θ /方案)适用于辐射探测器:薄膜、电荷耦合器件(CCD)和微通道板(MCP)。x射线薄膜用于器件工作范围(3/spl Aring/-18/spl Aring/)的光谱测量。器件工作范围由CCD测量。CCD长度为3cm。它对应于x射线光谱的/spl Delta//spl lambda/=4/spl Aring/范围。模拟CCD信号被转换成数字形式，并发送到IBM PC机。计算机软件中有等离子体参数测定代码(T/sub e/，n/sub e/)。对CCD在x射线区的特性进行了初步研究。本文给出了其中的一些结果。有两个时间分辨探测器用于等离子体动态测量。这些探测器的结构是基于微通道板。MCP探测器的x射线范围为/spl Delta//spl lambda/=0.1/spl Aring/。给出了该装置在脉冲功率装置ANGARA-5和GAEL上的一些应用结果。
