Paper Abstract

Absolute x-ray calibration of laser-produced plasmas was performed using a CCD linear array and a focusing crystal spectrometer. The plasmas were created by a Nd glass laser and a high repetition rate Nd-YAG laser. A commercial CCD was used for x-ray detection. The CCD linear array has 3724 pixels giving a total length of approximately 30 mm. First the CCD detector was absolutely calibrated using laser- produced plasmas and an FE55 isotope source. The sensitivity of the detector was about two orders of magnitude higher than x-ray photographic film. The CCD detector was used for monitoring the absolute x-ray yield, for finding the optical focal position, for estimating the flux density on the target and for measuring the electron temperature of the plasma. In combination with a focusing von Hamos spectrometer the detector was used for absolute spectral measurements and determination of the plasma parameters. This spectrometer is promising for absolute spectral measurements of x-ray radiation of low-intensity sources and for numerous practical applications.
