摘要
Filtered x-ray diode (XRD) detectors are used as primary radiation flux diagnostics on Sandia's Z accelerator, which generates nominally a 200-TW, 2-MJ, x-ray pulse. Given such flux levels and XRD sensitivities the detectors are being fielded 23 m from the source. The standard diagnostic setup and sensitivities are discussed. Vitreous carbon photocathodes are being used to reduce the effect of hydrocarbon contamination present in the Z-machine vacuum system. Nevertheless pre- and postcalibration data taken indicate spectrally dependent changes in the sensitivity of these detectors by up to factors of 2 or 3. (C) 1999 American Institute of Physics.
