Fast ion transport during applied 3D magnetic perturbations on DIII-D

Zeeland, M. A. van Ferraro, N. M. Grierson, B. A.

Measurements show fast ion losses correlated with applied three-dimensional (3D) fields in a variety of plasmas ranging from L-mode to resonant magnetic perturbation (RMP) edge localized mode (ELM) suppressed H-mode discharges. In DIII-D L-mode discharges with a slowly rotating n = 2 magnetic perturbation, scintillator detector loss signals...

Modulation of prompt fast-ion loss by applied n=2 fields in the DIII-D tokamak

Zeeland, M. A. van Ferraro, N. M. Heidbrink, W. W.

Energy and pitch angle resolved measurements of escaping neutral beam ions (E approximate to 80 keV) have been made during DIII-D L-mode discharges with applied, slowly rotating, n = 2 magnetic perturbations. Data from separate scintillator detectors (FILDs) near and well below the plasma midplane show fast-ion losses correlated with the...
