Application of charge coupled devices as spatially-resolved detectors for X-ray spectrograph

An X-ray crystal spectrograph which contains a CCD linear array as the position-sensitive detector is described. Radiation detection is performed directly onto CCD. The spectrograph has a limit of sensitivity at about 2 J/(A.ster), spectral resolution about 1000 and dynamic range 100-120. The device operates on-line with IBM-PC based control system. Software provides all data acquisition and treatment. Output spectra are presented in absolute units. The device was used during composite Z-pinch experiments at pulse-power installations ''Angara-5-1'' (TRINITI, Troitsk, Russia) and ''GAEL'' (Ecole Polytechnique, Palaiseau, France). Currently the spectrograph is included in the set of diagnostics of the ''Angara-5-1'' facility. Some of the spectra obtained are presented and discussed. (author). 4 figs., 9 refs
