Wall conditioning in ITER

Abstract

This article presents plans for wall conditioning for ITER. Typical machine parameters are 1.5 GW of fusion power and 1000 s of DT burn duration. To achieve these plasma, the wall conditioning is required in ITER. For baseline methods, glow discharge cleaning for zero-magnetic field, and electron cyclotron resonance discharge cleaning and divertor active pumping for high-magnetic fields are considered. Alternative methods are also considered.
