Title: Note: Characterization of a high-photon-energy X-ray imager

The Bragg angle, rocking curve, and reflection efficiency of a quartz crystal x-ray imager (Miller indices 234) were measured at photon energy of 15.6909 keV, corresponding to the K{sub α2} line of Zr, using the X15A beamline at the National Synchrotron Light Source at Brookhaven National Laboratory. One flat and three spherically curved samples were tested. The peak reflectivity of the best-performing crystal was determined to be (3.6 ± 0.7) × 10{sup −4} with a rocking-curve full width at half maximum of 0.09°. The Zr K{sub α2} emission was imaged from a hot Zr plasma generated by a 10-J multiterawatt laser.
