摘要
Experiments and theory characterize the novel chaotic neoclassical transport scaling as nu B-0(c)-1 in contrast to traditional collisional neoclassical transport scaling as nu B-1/2(c)-1/2. This chaotic transport occurs when local trapping separatrices have theta-variations or temporal fluctuations. Experiments observe bulk particle transport, damping of Langmuir waves and diocotron waves, and nonlinear wave-wave couplings. These effects may be important in low-collisionality fusion plasmas.
