Abstract
The self protecting nature of the vapor shield mechanism is important for prediction of surface damage caused by disruptions or run away events in tokamaks. We report on detailed modeling and experimental analysis of the vapor shield (VS) mechanism. The energy transmission factor f through the VS boundary layer is found to be surprisingly low (about 10%) which may reduce estimates for the surface damage.Keywords
