摘要
Turbulent diffusion of electrons in drift modes in a sheared magnetic field is studied by using a test particle numerical experiment. Electrons diffuse across the magnetic field over mode rational surfaces, where electrons interact with waves in resonance. A spatial diffusion coefficient, which describes resonance broadening, is found to be time dependent and departs from quasilinear predictions in stronger turbulence even well before the time when particles hit the resonance boundary of the rational surfaces. © 1990 American Institute of Physics.
