An evaluation of kinetic eects in the DIII-D divertor
Under certain conditions, high temperature electrons diusing across the separatrix near the midplane can propagate to the divertor without collision and produce a high energy tail in the electron distribution function near the separatrix. We evaluate a kinetic criterion along the ®eld using measurements from divertor Thomson scattering and compare temperature measurements from target plate Lan...
متن کاملDivertor Plasma Physics Experiments on the Diii–d Tokamak
DIVERTOR PLASMA PHYSICS EXPERIMENTS ON THE DIII–D TOKAMAK. In this paper we present an overview of the results and conclusions of our most recent divertor physics and development work. Using an array of new divertor diagnostics we have measured the plasma parameters over the entire divertor volume and gained new insights into several divertor physics issues. We present direct experimental evide...
متن کاملFlow reversal, convection, and modeling in the DIII-D divertor
Measurements of the parallel Mach number of background plasma in the DIII-D tokamak divertor @M. A. Mahdavi et al. in Proceedings, 16th International Conference, Montreal, 1996 ~International Atomic Energy Agency, Vienna, 1997! Vol. I, p. 397# were performed using a fast scanning Mach probe. The parallel particle flow shows evidence of complex behavior such as reverse flow, i.e., flow away from...
متن کاملTransport of Elm Energy and Particles into the Sol and Divertor of Diii–d
We report on DIII–D data that reveal the underlying processes responsible for transport of energy and particles from the edge pedestal to the divertor target during Type I edge-localized modes (ELMs). The separate convective and conductive transport of energy due to an ELM is determined by Thomson scattering measurements of electron density and temperature in the pedestal. Conductive transport ...
متن کاملAn experimental comparison of gross and net erosion of Mo in the DIII-D divertor
Experimental observation of net erosion of molybdenum being significantly reduced compared to gross erosion in the divertor of DIII-D is reported for well-controlled plasma conditions. For the first time, gross erosion rates were measured by both spectroscopic and non-spectroscopic methods. In one experiment a net erosion rate of 0.73 ± 0.03 nm/s was measured using ion beam analysis (IBA) of a ...
