Electric conductivity in tokamaks and extended neoclassical theory

Technical Report:

Abstract

Electric conductivity measurements reported for various tokamaks are compared with both the usual neoclassical theory and with an extended neoclassical theory where the electron-electron collision rate is anomalous while the electron-ion collision rate remains coulombian. It is found that, out of the 14 experiments considered, 3 are consistent with both the neoclassical and the extended neoclassical theories; 4 are consistent with neoclassical theory and also, within the experimental errors, not inconsistent with the extended neoclassical theory; 4 experiments are consistent only with the extended neoclassical theory; the remaining three experiments appear to be incompatible with both theories. It is concluded that the extended neoclassical theory, which accommodates naturally an anomalous electron thermal conductivity, is a serious candidate for explaining tokamak experiments.
