Plasma Application Technology for Contamination Control in Fusion Devices: A Brief Review
Original language description
The presence of impurities in tokamak systems is a significant concern,as it leads to heat loss and reduced overall efficiency. While liquid metal divertorsare highly efficient, they face the challenge of redeposition, necessitating frequent andrigorous cleaning of the tokamak vessel. Contamination from evaporation, deposition,and redeposition processes further complicates vessel maintenance, underscoring the needfor effective decontamination strategies. Over the past decades, extensive research hasvalidated several wall conditioning and cleaning techniques to address these issues.Thisreview provides a comprehensive discussion of four key plasma-based decontaminationmethods that have been studied and validated for tokamak cleaning applications. Thesemethods include the Glow Discharge Cleaning system, plasma cleaning of ITER firstmirrors, ECR plasmas for wall conditioning in the HT-7 tokamak, and the conditioningof the SST-1 Tokamak Vacuum Vessel through baking and glow discharge cleaning. Thereview highlights the crucial role of plasma applications in the cleaning processes oftokamak vessels, demonstrating their effectiveness in maintaining system performance.
