Short pulse laser coupling efficiency to hot electrons for fast-ignition studies.

ORAL

Abstract

Experiments were performed at the Titan laser facility at LLNL to study energy coupling efficiency to hot electrons as a function of irradiation conditions and target geometry. Hot electron spectra from cone and slab targets are compared and correlation with their K shell emission spectra is examined.
