“Dynamics of strongly kinked, low edge safety factor tokamak plasmas in the Madison Symmetric Torus”

Monday, October 25th at 4:00pm

Current-carrying toroidal fusion plasma devices can be characterized by the edge safety factor q(a), which is proportional to the ratio of toroidal field to plasma current. Tokamaks typically suffer “disruptions” or terminations due to the kink instability when q(a) < 2. Presented here are experiments in the Madison Symmetric Torus (MST) at the Wisconsin Plasma Physics Laboratory (WiPPL) in which tokamak discharges are sustained with q(a) < 2, thus filling the gap between reversed-field pinch and tokamak operation.
