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.
