Temperature anisotropy and rotation upgrades to the ICRF modules in SNAP and TRANSP

PDF Version Also Available for Download.

Description

Fokker-Plank and transport codes have significantly better velocity-space treatment of the plasma than do the RF deposition models: FPP uses a 2 or 3D velocity space calculation, TRANSP uses Monte-Carlo particles, e.g., 3D in velocity space, many 2 and 3D spatial RF deposition codes are based on Maxwellians, with a single velocity-space parameter, i.e., the isotropic temperature. The ultimate goal of this effort was to provide the deposition codes with better velocity-space physics. For ICRH heating on TFTR, two important physics issues are velocity-space anisotropy (because of high energy tails), and plasma rotation (because of simultaneous NBI-RF heating). In addition, ... continued below

For ICRH heating on TFTR, two important physics issues are velocity-space anisotropy (because of high energy tails), and plasma rotation (because of simultaneous NBI-RF heating). In addition, these two physical effects are among the suite of experimentally measurable quantities, and most of the required new formulas already exist in the literature.
