INFLUENCE OF BORONIZATION ON THE PLASMA PERFORMANCE IN TEXTOR
The plasma-facing surfaces of TEXTOR have recently been coated with a thin layer of hydrogen rich carbon and boron in the ratio (1:1). An improved plasma performance results when this coating replaces the amorphous carbon layer used before. The main differences are a pronounced reduction of the radiation losses, a decrease of Z(eff) from 1.4 to 1.2 and a significant change in the hydrogen recycling. Possible explanations for the reduction of the oxygen concentration and for the change in hydrogen recycling are suggested and discussed.
