Abstract

Narrowband x-ray imagers using spherically bent crystals have been implemented on all three laser facilities (MTW, OMEGA EP, and OMEGA) at the University of Rochester’s Laboratory for Laser Energetics. These spherical crystal imagers (SCI’s) use a 150-μm-thick, 25.4-mm-diam quartz crystal cut either along the 2131 plane to reflect the Cu K_α line at ∼8 keV with a Bragg angle of 88.7^° or along the 1011 plane to reflect the Si He_α line at ∼1.865 keV with a Bragg angle of 83.9^°. The SCI systems can be set up to either image the self-emission of a laser-heated target or to backlight a high-energy-density plasma object.
