Charge-Exchange Measurements of Parallel and Anti-Parallel Ion Temperature Profiles on ATC.

摘要

This paper describes measurements of the ion temperature profiles parallel and anti-parallel to the plasma current in the ATC tokamak. The measurements were made using a single energy channel multi-sight-line neutral particle detector. The anti-parallel profile was found to be parabolic or somewhat broader,in accordance with expectation,while the parallel profile was nearly flat from the plasma center to within a few centimeters of the edge. This difference between the two profiles is interpreted as being due to neoclassical effects associated with large banana orbits. (ERA citation 03:034141)
