Multicolor Soft X-Ray Imaging of $Z$-Pinch Radiation Sources on the Z-Machine Pulsed-Power Driver

Time-resolved X-ray pinhole imaging is employed for diagnosing fast Z-pinch implosions on the Z accelerator. Reflection from a multilayer mirror produces monochromatic 277-eV images of the Z-pinch plasma in the final stages of implosion and stagnation. Simultaneous imaging with a filtered pinhole camera or using a second mirror can yield multicolor X-ray images which contain spectral as well as spatial information, allowing for the study of radiation physics in dense Z-pinches.
