Nevada Shocker is a 540KV, 7O, 50ns, pulsed power device based on Marx Bank and Blumlein technologies. When this machine fires, the energy is funneled to a plastic insulator supported by two circular electrodes. The purpose is to study the surface breakdown properties of the plastic. It is hypothesized that a thin layer of gas exists between hard vacuum and the solid. The goal is to determine change in the gas profile and suggest how it may contribute to surface flashover; Stimulated desorption techniques such as photon stimulated desorption and thermal stimulated desorption are employed in characterizing the gas profile. The plastic under test is Rexolite. A vacuum system with Rexolite plastic is brought down to pressure levels of 10-8 to 10-9 Torr to study the presence of the thin layer of select gas molecules. A Nd: YAG pulsed laser is used to stimulate the surface of the plastic under vacuum.
