Research Goal

High-intensity laser-material interactions can create tremendous space charge effects at the surface of a target, creating an electric field that can greatly exceed 10 6 V/m that shifts the electronic energy states of the surface material. We investigated the effect of applied fields on thermal emission from surfaces by constructing a unique Hohlraum in which known electric fields can be applied to the surface. The results of this work were inconclusive, in that we were unable to apply high enough fields to polarize the carbon surfaces of the Hohlraum (order 10 4 V/m). We published two papers on the system and a paper comparing absorption and emission Monte Carlo methods for finding the system's effective emissivity. (NSF)
