Abstract

During ITER lifetime, dusts and flakes will be produced due to the interaction of plasmas with the in-vessel materials or due to maintenance. They will be made of carbon, beryllium and tungsten and will be activated, tritiated and chemically reactive and toxic. Safety limits have been set in order to reduce dust hazards. Thus, dust diagnostics and removal methods need to be developed for ITER considering the constraints linked to magnetic field, radiation, vacuum and temperature. This paper reviews potential diagnostics to monitor the dust content based on erosion, deposition or dust in suspension measurements using optical, sampling or gravimetric systems. © 2008 Elsevier B.V.
