Ten Channel Filter-Fluorescer Spectrometer

摘要

A ten channel filter-fluorescer spectrometer was designed for measuring x-ray spectra from 2 to 115 keV at the Argus and Shiva laser facilities. Previously x-ray spectra were measured with filtered detectors; however, the higher fluxes and more complicated spectra observed in recent experiments requires the greater photon energy definition of this technique. Five filter-detector channels are also incorporated in the spectrometer for measuring low intensity sources. Five Pb-filtered detectors will be used for obtaining spectral information for energies greater than 100 keV. Provisions are being made to automate this diagnostic to produce the x ray spectrum minutes after shot time. (ERA citation 04:014389)
