The spectral characteristics of plasma radiation of a gas Z-pinch with a rise time of 1 s and a current amplitude of 250 kA have been measured. The measurements were performed in the range of X-ray energy quanta from 30eV to 600 eV. A spectrograph with a transmission grating and a polychromator on the basis of multilayer X-ray mirrors served as the diagnostic devices. Absolutely calibrated semiconducting detectors AXUV-5 were used as radiation detectors in the polychromator. The full pinch radiation loss was measured with a thermocouple calorimeter. The radiation of He-, Li- and Be- like ions has been shown to dominate at the stage of maximum compression of the nitrogen Z-pinch. The results of the spectral measurements were employed for the absolute calibration of various X-ray detectors.
