摘要:The effects of recycled neutral atoms on tokamak ion temperature gradient (ITG) driven turbulence have been investigated in a steep edge pedestal, magnetic separatrix configuration, with the full- f edge gryokinetic code XGC1. An adiabatic electron model has been used; hence, the...

摘要:Previously the gyrokinetic neoclassical code XGCa found that the pressure balance (or momentum balance) in the diverted scrape-off layer (SOL) does not follow that from the fluid description based on the Chew–Goldberger–Low (CGL) theory. In this paper a gyrocenter parallel m...

摘要:Simulations using the fully kinetic neoclassical code XGCa ( X -point included g uiding- c enter a xisymmetric) were undertaken to explore the impact of kinetic effects on scrape-off layer (SOL) physics in DIII-D H-mode plasmas. XGCa is a total- f , gyrokinetic code which se...

摘要:Neutral particle behavior in Aditya tokamak, which has a circular poloidal ring limiter at one particular toroidal location, has been investigated using DEGAS2 code. The code is based on the calculation using Monte Carlo algorithms and is mainly used in tokamaks with diverto...

摘要:In order to understand the atomic and molecular processes involved in the emission of the hydrogen Balmer alpha (H) spectral line from tokamak plasmas, the measured radial profile of H emissivity in ADITYA tokamak discharges has been modeled using the DEGAS2 neutral particle...

摘要:This paper describes the range of variations in edge and SOL turbulence observed using a gas puff imaging (GPI) diagnostic in NSTX discharges. The database consists of 140 shots including Ohmic, L-mode, and H-mode plasmas measured during steady-state conditions (e.g. without...

摘要:Lithium-coated high- Z substrates are planned for use in the NSTX-U divertor and are a candidate plasma facing component (PFC) for reactors, but it remains necessary to characterize the gross Li erosion rate under high plasma fluxes (>1023 m−2 s−1<...

摘要:While intermittent filamentary structures, also known as blobs, are routinely seen in the low-field-side scrape-off layer of the National Spherical Torus Experiment (NSTX) (Ono et al 2000 Nucl. Fusion 40 557 ), fine structured filaments are also seen on the lower dive...

摘要:This review summarizes the presentations and discussions by experts in the fields of edge plasma physics and plasma–material interactions at a workshop organized for the purpose of evaluating current status and extrapolating forward to the post-ITER power plant regime. The t...
