Simulation of the Ion-Beam-Driven Drift Instability in a Magnetic Trap II
Abstract
Recent Experiments on the TMX-U device at LLNL have indicated the possibility of a low frequency drift wave being driven unstable by the injection of neutral beams in the thermal barrier region. Nonlocal linear theory is performed for this instability using slab geometry and the electrostatic approximation. Particle simulations are used to verify the linear theory and to recover relevant nonlinear phenomena. Important nonlinear effects include: (1) ExB trapping (2) relaxation of the beam density profiles, and (3) weakly nonlinear electrons.
