- Abstract
- Modified Reversed-Field eXperiment is an experiment of magnetic confinement of thermonuclear plasma in the Reversed-
Field Pinch configuration. The toroidal device is designed to operate with hydrogen plasmas, and the most internal wall is
entirely covered with polycrystalline graphite tiles. The disadvantage of graphite walls is the progressive hydrogen accumulation
in graphite during operation. To overcome this problem, some graphite conditioning procedures are necessary (e.g.
boronization, lithization and glow discharge). The critical role of graphite walls on plasma control suggested the use of
secondary ion mass spectrometry (SIMS) technique for the evaluation of conditioning procedures efficacy. SIMS analyses of
graphite samples after their exposure to plasmas or wall conditioning treatments are presented in this work. The SIMS
technique resulted fundamental on the investigation of the boron distribution in the graphite tiles, and sample comparisons
indicated the need for glow discharge cleaning system upgrading to improve the conditioning process and boronization
uniformity (literal)
