Laser plasma pulse source of soft X-ray for calibration

The high intensity pulse source of soft X-ray for calibration was formed with multilayer mirror as dispersive elements and laser plasma interaction as X-ray source. The monochromator system with 4 channels was set up and its performance was studied on SGⅡ high power laser facility experiment. The experiments included measurement of source intensity and stability, consistency of related channels and so on. Photon energy of source is 253 eV with 1.8×1019 photon/(s·cm2) source intensity and 820 eV with 3.2×1019 photon/(s·cm2) source intensity. The results show that the source can be used to calibrate XRD, mirror, multilayer, transmission grating and filter.
