Abstract

Johann and DuMond quartz crystal focusing spectrometers are proposed for hard x-ray spectra investigations of sub-ps laser-produced plasmas when the source is located on the focal circle. Because the crystal intercepts and focuses a large solid angle of radiation, the schemes have extremely high efficiency, which could be 10³ times higher than those of flat crystal spectrometers. Due to the small size of the source the schemes have a high spectral resolution. By using reflection and transmission modes, the schemes cover a very wide spectral range: 0.2-2.3 angstrom. Curved quartz crystal is tested in the reflection mode using Fe K_(alpha ) radiation.
