Rapid cleaning of boronized walls with a chlorine/hydrogen glow discharge
- 1. Nagoya Univ. (Japan). Faculty of Engineering
Description
Chlorine/hydrogen discharge cleaning was developed to remove boron films coated on walls of nuclear fusion devices. The removal rate of boron films (∼0.1 A/s) was an order of magnitude faster than that obtained by conventional hydrogen discharges. Mass spectroscopic measurement revealed that BCl3 is a main volatile product in the removal process. Chlorine contaminants after film removal were cleaned up by additional hydrogen discharges.
