摘要
Cross field heat and particle transport due to the thermally excited convective cell mode is investigated both by theoretical work and by particle simulations. It is shown that there is a parameter range where the heat diffusion coefficient DH is considerably less than the particle diffusion coefficient DP. This results from the fact that high energy particles in a velocity distribution diffuse much more slowly than the low energy particles because the fluctuating electric fields are averaged over their finite Larmor radii. The magnetic field scaling of DH⁄DP is also discussed. The results imply that ions in a thermonuclear reactor should be less affected by turbulence than are electrons as appears to be the case. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
