Magnetic Spectra and Electron Transport of Current-Carrying Plasmas

A statistical theory for the properties of current-carrying plasma is postulated. The small-scale magnetic turbulences are isotropic in $\overrightarrow{\mathrm{k}}$ and have a wave-number spectrum similar to that of black-body radiation. The electron transport coefficient is found to have an $n^{-1\mathrm{}}$ dependence and a numerical value remarkably close to that of the empirical Alcator scaling. The frequency spectrum (as seen by a magnetic probe) is also calculated and is in good agreement with experimental results. Some unresolved questions are discussed.
