Kinetic modeling of neutral transport for a continuum gyrokinetic code
T. N. Bernard, F. D. Halpern, M. Francisquez +6
We present the first-of-its-kind coupling of a continuum full-f gyrokinetic turbulence model with a 6D continuum model for kinetic neutrals, carried out using the Gkeyll code. Our…
Kinetic fluid moments closure for a magnetized plasma with collisions
R. E. Waltz, F. D. Halpern, Z. Deng +1
A novel method aimed at a kinetic moments closure for a magnetized plasma with arbitrary collisionality is proposed. The intended first application is to a tokamak edge and scrape-…
Plasma Turbulence in the Scrape-off Layer of the ISTTOK Tokamak
Rogerio Jorge, Paolo Ricci, Federico D. Halpern +2
The properties of plasma turbulence in a poloidally limited scrape-off layer (SOL) are addressed, with focus on ISTTOK, a large aspect ratio tokamak with a circular cross section.…
Statistical analysis and modeling of intermittent transport events in the tokamak SOL
J. Anderson, F. Halpern, P. Xanthopoulos +2
The turbulence observed in the scrape-off-layer of a tokamak is often characterized by intermittent events of bursty nature, a feature which raises concerns about the prediction of…
