“Dust in Fusion Plasmas” by Professor John Goree, Department of Physics & Astronomy, The University of Iowa

Abstract: The plasma-facing walls within nuclear-fusion reactors are exposed to a very severe exposure that leads to erosion of the wall material. This erosion generates small solid particles (dust) that become immersed in the edge of the plasma in the reactor. These solid particles pose a contamination problem that must be limited. In this talk I review the basics of tokamak fusion reactors and I review experiments, performed by other researchers at major facilities, to observe the generation and transport of  dust in tokamak edge plasmas
