WITHDRAWN--Core Temperature and Density Maps of Direct Drive Implosions using Multispectral X-ray Imaging*

We report on the experiments to obtain core temperature and density maps in direct drive implosions performed at the OMEGA laser facility using a multi-monochromatic X-ray imager, consisting of an array of pinholes and a flat multilayer mirror, providing unique multi-spectral images distributed over a wide spectral range. Employing Ar as a dopant in the DD-filled plastic shells produces emission images in the Ar He-$\beta $ and Ly-$\beta $ spectral regions. These images allow the retrieval of temperature and density maps of the imploding core. Using three identical imagers in a quasi-orthogonal line-of-sight geometry we obtain three-dimensional profiles and images of the cores in different temporal intervals. Temperature and density profiles will be presented and compared with earlier works on direct- and indirect-drive. [UCRL-ABS-213695]
