A spectrometer has been developed to meet the requirements of the x-ray laser effort at Lawrence Livermore National Laboratory (LLNL). The instrument takes advantage of the intrinsically small divergence and size of the lasing source by putting it, the grating, and the detector on the Rowland circle. This design obviates the need for a slit but makes the target chamber an integral part of the spectrometer. Sensitivity is maximized by intercepting the entire laser footprint, by keeping the angle of incidence upon the grating at about 70/sup 0/ to the normal, and by single-photon detection capability at the detector plane. Signal to background is greatly improved by gating the spectrometer at the subnanosecond level, using three stripline structures deposited on the microchannel plate detector. The sum of incident and diffracted angles is kept constant. By using simple spacers and custom ruled gratings any energy in the 65--200 eV range is accessible.
