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.
