Abstract
We present details of an absolutely calibrated twin channel x-ray spectrometer employing elliptically curved x-ray analyzer crystals. The spectrometer utilizes high-energy cut-off grazing incidence mirrors, low-energy cut-off K-edge filters and a stable of analyzer crystals including naturally occurring crystals and molecular multilayers, allowing coverage of the spectral region from 100 to 10,000 eV with a resolution of - 3 eV. One channel of the spectrometer is recorded on photographic film; the second is coupled to an x-ray streak camera of novel design which incorporates a large aperture (40 mm) photo-cathode and has a time resolution of less than 10 ps. All of the components of the spectrometer have been absolutely calibrated using a monochromatic D.C. x-ray source and proportional counter system. By cross-calibrating the time-resolving channel with the time integrating channel we obtain absolutely calibrated time-resolved spectra. This instrument has been used extensively to diagnose laser-produced plasmas at the University of Rochester's Laboratory for Laser Energetics. In this paper we will present some typical time-resolved spectra to illustrate the capabilities of the spectrometer, its sensitivity and wide application. In addition, we discuss the performance characteristics of the x-ray streak camera design.
