Abstract

Glow discharge cleaning (GDC) in mixtures of O₂ and He was applied in TEXTOR for about 4 h to study the removal of redeposited carbon layers. The behaviour of the formation of volatile carbon oxides (CO and CO₂) and its dependence on the O₂ injection rate and on the addition of He into the O₂ GDC are described. Carbon (5.22 g) was removed from TEXTOR in about 4 h GDC corresponding to a carbon removal rate of ∼2.1 × 10¹⁹ C/s. Plasma recovery was obtained after wall cleaning in H₂ GDC and finally by boronisation.
