Abstract :
Summary form only given. We are now performing imploding annular wire-array experiments on the PBFA-Z accelerator. The experimental diagnostics include X-ray diode detectors (XRDs), photoconducting diode detectors (PCDs), and X-ray pinhole cameras both time-integrating and time-dependent. We have set up a pulsed-laser x-ray source for calibration of these diagnostics. A pulsed 10-joule Nd:YAG laser is shot onto a low-Z target, and a combination of filters then provides a large-area, mono-energetic source with a one-nanosecond pulse width. Measurements of the diagnostic´s sensitivity between 160 eV and 3 keV can be determined with this source with the appropriate combination of target and filter. The reference standard is a 1024/spl times/1024 pixel X-ray CCD that measures the source intensity and is calibrated at 100 eV to 2500 eV.
