Abstract
The high divertor heat load during a tokamak plasma disruption results in sudden evaporation of a thin layer of divertor plate material, whi ch acts as vapor shield and protects the target from further excessive evaporation. Formation and effectiveness of the vapor shield are theo retically modeled and are experimentally analyzed at the 2MK-200 facil ity under conditions simulating the thermal quench phase of ITER tokam ak plasma disruptions.
