Simulation of erosion of the tungsten wall by impurities in the divertor plasma
Divertor is a component that directly contacts the plasma in tokamak. To ensure the lifetime of the device, it is necessary to reduce the erosion of the divertor wall by plasma. In this work, a particle-in-cell model is used to study the influences of plasma temperature and impurity concentration on the erosion of tungsten divertor wall by carbon and beryllium ions. The steady-state sheath, particle and energy fluxes to the wall, and the energies and angle of the incident ions can be obtained.doi:10.7498/aps.63.145204 fatcat:z3qw3s4pnrervkjqcsovv5ey34
