Elliptically bent crystal spectrograph for X ray diagnosis of laser produced pla

In order to measure spatially and temporarily resolved laser-produced plasma X-ray spectra in 0.2-2 nm region, a novel two-channel elliptically-bent crystal spectrograph has been developed. Dispersive elements are LiF, PET, Mica, and KAP crystals, which cover Bragg angles in the range of 30-67.5 deg
