Flutter interpretation of thermal conduction with application to Alcator

A previously presented magnetic fluctuation interpretation of anomalous thermal conduction in Tokamaks is extended to the high field, high density regime of Alcator. Density fluctuations are fully taken into account but found not to significantly alter the predictions. If the electron parallel thermal conductivity is corrected for high Knudsen number effects, the authors find that the mean squared relative magnetic fluctuation level must scale as (density) -2 , to fit Alcator scaling.
