A shock-tube study of fusion plasma-wall interactions
Abstract
The paper describes phenomena which occur when a hot dense deuterium plasma containing a transverse magnetic field is brought into sudden contact with a cold metal wall. High-energy electromagnetic shock-tube experiments and computational simulation studies are reported. The rate of energy transfer from the plasma to the wall is calculated, and conditions under which surface melting occurs are estimated. Experimental measurements are in good agreement with computed values. The effects of exposure of fusion reactor first-wall materials to 6.0 times 10 to the 21st power eV/sq cm are described.
