Determination of the Rocking Curve and Reflection Efficiency of a Quartz Crystal X-ray Imager

A spherically curved Bragg crystal was characterized for use in experiments utilizing the Kα emissions of higher Z materials than current crystals allow. The National Synchrotron Light Source at Brookhaven National Laboratory was used to study the crystal with x-rays of energies 15.6909 keV, 16.5210 keV, 17.4793 keV, and 22.1629 keV corresponding to Zr Kα2, Nb Kα2, Mo Kα1 and Ag Kα2 emissions, respectively. The crystal was then used to image the Kα emission from a Zr target irradiated using the multi-terawatt laser at the University of Rochester. In conclusion the crystal was a successful diagnostic, and provided the first ever image of Zr Kα radiation.United States of America Department of EnergyNo embarg
