Kinetic study of sheath region near the first wall for tokamak fusion reactors
Creators
Description
Theoretical profiles of density, temperature, drift velocity, and electric field are calculated for the sheath region between the plasma and first wall of a tokamak fusion reactor. It is shown that gyro-orbit effects on charged particle diffusion across the magnetic field create a sheath potential of 6 e/phi/sub k/T/sub e/ that strongly repels ions. This effect becomes important in the evaluation of sputtering and secondary electron emission at the first wall due to ion bombardment
