Abstract : Science Research Laboratory, inc. (SRL) had designed, assembled and tested a new suite of X-ray instruments for the PHOENIX radiation simulator. This suite consists of an X-ray pinhole camera, an XUV pinhole camera and an X-ray crystal spectrometer. All three instruments were designed to be located within approx. 2 - 3 m of a terawatt class simulator plasma. The instruments provide 0.2 ns continuous time resolution, approx. 0.25 mm spatial resolution and a wide dynamic range of approx. 1000:1. This suite is also capable of measuring the power radiated by the pinch anywhere in a approx. 1 microsecs window, including the very soft (100-900 eV), XUV radiation emitted during the early part of the implosion, and ending with the approx. 20 ns burst of L- or K-shell X-radiation from different elements. in the 1-15 keV band. The three instruments were assembled, tested, and calibrated using an available 10-20J/pulse X-ray point source of neon K-shell X-rays. To keep costs down, SRL utilized the similarity between the X-ray and XUV pinhole cameras (described in detail later in this report) to build one camera body capable of use both an X-ray and an XUV pinhole camera. In parallel, subcontractors developed and delivered a 224 channel fast array digitizer package with interfaces to the analog output of the SRL suite. Software was also developed to archive data from the digitizer channels and provide preliminary analysis and displays. This suite was installed on PHOENIX and validated.
