Electron thermal conductivity and diffusion in a tokamak
Merezhkin V. G., Mukhovatov V. S.
The dependence of the electron thermal conductivity in a tokamak on the toroidal ratio r/R and on the major radius R is discussed. It is shown that the energy lifetimes of electrons measured in different devices agree with the dependence rEe~R 3It is also shown that the experimental data are consistent with the dependence D s^ffJ where к —0.1.
