The stability of electric charge adsorbed on a fused quartz surface has been studied. In particular, the effects of electric field strength, radiation, and ambient gas pressure have been investigated. It is found that transfer to or from the surface of sufficient charge to neutralize an external electric field occurs readily under ultraviolet radiation. Evidence is presented that changes in surface charge in the presence of a gas ambient occur when the electric field at the surface exceeds the breakdown field of the gas. Partial discharges then occur which alter the surface charge in such a way as to reduce the field below the breakdown value. Author
