Abstract

Impurity control, especially during auxiliary heating, is still one major issue in fusion devices. Though it has been possible to reduce appropriate choice of wall and limiter materials or by using divertors, their origin is still under discussion. The contribution of charge working gas from hydrogen to helium, where CX cross sections are much lower. The contribution of ion sputtering can be investigated by comparison of divertor and carbon limiter discharges.
