متن کاملMomentum transport and flow damping in the reversed-field pinch plasma
A biased electrode is used in the Madison Symmetric Torus ~MST! reversed-field pinch @Fusion Technol. 19, 131 ~1991!# to manipulate plasma flow in order to study flow damping and momentum transport. Finite radial conductivity allows a radial current, which provides the toroidal torque that spins up the plasma. The applied torque is balanced by a viscous force that opposes toroidal flow accelera...
متن کاملTwo Fluid Dynamo and Edge-Resonant m=0 Tearing Instability in Reversed Field Pinch
Current-driven tearing instabilities dominate magnetic relaxation in self-organized high temperature plasmas such as the reversed field pinch (RFP) and spheromak. In the Madison Symmetric Torus (MST) RFP experiments, they are observed in the form of magnetic field, flow velocity, and current density fluctuations that follow a temporally cyclic sawtooth behavior. During a sawtooth crash, a surge...
