Abstract :
The X-ray spectrograph based on mica crystal (2d=19.9Å) for spectrum analysis is described. The device construction (θ-2θ 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 (3Å-18Å). The device working range is measured by CCD. The CCD length is 3 cm. It correspond to the Δλ=4Å 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 (Te,ne). 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 Δλ=0.1Å. Some results of this device application at the pulsed power facilities ANGARA-5 and GAEL are given
