Abstract
Panels made out of 304 SS, Mo, Inconel 600, α-Ti and Ti6A14Mo were installed on the outer walls in Microtor II and heated up to a maximum temperature of 800°C. No significant H α-light emission was observed near the hot panels during tokamak discharges. When carefully outgassed and properly surface conditioned (Ti deposition and discharge cleaning), these hot surfaces do not have a deleterious impact on tokamak discharges. Carbon originating from the bulk materials is the most abundant impurity that accumulates on the hot surfaces. Ti layers at 800°C are able to retain bulk oxygen, but carbon can diffuse out of the substrate materials and through the film to segregate at the Ti-vacuum surface. Inconel 600 substrates released the smallest amount of carbon during discharges. Impurity control with Ti, deposited onto cold panels, remains beneficial even at higher temperatures. Previously observed long term effects such as flaking and peeling are avoided due to interdiffusion of Ti and the panel matrix. Furthermore, hydrogen retention is eliminated.
