Boronization in the HL-1M tokamak
- 1. Southwestern Inst. of Physics, Chengdu (China)
Description
The inner wall of the HL-1M vacuum chamber has been coated in situ with a boron-containing carbon film by means of DC glow discharge in helium and carborane. The average film thickness is 50-70 nm and the ratio of boron to carbon in the layer is about 1:6. Wall conditions are improved dramatically by boronization. Oxygen from the wall was suppressed significantly and the chemical erosion of graphite tile surface by energetic hydrogen ions/atoms seemed to be reduced also. Some plasma parameters, the stability and reproducibility of discharges and LHCD operating conditions were improved greatly after boronization
