Charles H. Skinner was involved in tritium retention issues on TFTR and invented and demonstrated a novel laser-based detritiation technique. He also invented and demonstrated a novel electrostatic dust detector in the National Spherical Torus Experiment-Upgrade Tokamak and a novel laser-based method for cleaning first mirrors for ITER. He is involved in application of scanning auger microscopy to investigate wetting by lithium at a nanoscale level. Besides the fundamental interest of understanding wetting on an atomistic scale, this work has practical relevance to the development of liquid metal plasma facing components for managing plasma wall interactions in the extreme environment of high heat and particle fluxes in a magnetic fusion device.
