Abstract
Two quartz (10-11) crystals were cylindrically bent to 25.4 cm radius of curvature and were mounted in identical Cauchois type transmission spectrometers, and the crystal diffraction efficiencies were measured to 5 % absolute accuracy using narrow bandwidth x-ray source fluences in the 20 keV to 80 keV energy range. The measured integrated reflectivity values were compared to calculations performed using a computational model that accounts for the diffraction geometry of the bent transmission crystal. These crystal calibrations enable the accurate measurement of absolute hard x-ray emission levels from laser-produced plasmas and other laboratory sources.Citation
