Fast Electron Transport and Spatial Energy Deposition into Imploded High Density Plasmas using Cu-Doped CD Shell Targets

Fast electron spatial energy deposition is investigated in integrated cone-guided FI experiments by measuring fast electron induced Cu K-shell fluorescence emission using Cu doped CD shells attached to the Au cone. This work used the OMEGA laser (3$\omega $, 18 kJ) for fuel assembly, and a high intensity OMEGA EP beam (1$\omega $, 10 ps, 0.5 - 1.5 kJ, Ip \textgreater 1e19 W/cm2) focused onto the inner cone tip to produce fast electrons similar to previous FI heating experiments. Results showed an enhancement of 60{\%} in the total K$\alpha $ yield from the joint shots compared to driver only shots. Comparison of high and low contrast OMEGA-EP shots show enhancement in energy coupling with higher contrast. Experiments are modeled using LSP for fast electron generation and transport with DRACO predicted fuel assembly.
