Plasma diagnostic calibrations and characterizations at National Security Technologies´ High Energy X-ray calibration Facility

Summary form only given. National Security Technologies´ high energy X-ray (HEX) facility is unique in the U.S. Department of Energy complex. The HEX provides fluorescent X-rays of 5 keV to 100 keV with fluence of 10⁵-10⁶ photons/cm²/second at the desired line energy. Low energy lines can be filtered, and both filters and fluorescers can be changed rapidly. We present results of calibrating image plates (sensitivity and modulation transfer function), a Bremsstrahlung spectrometer (stacked filters and image plates), and the National Ignition Facility´s filter-fluorescer experiment (FFLEX) high energy X-ray spectrometer. We also show results of a scintillator light yield and alignment study for a neutron imaging system.
