Collisional theory of electrical resistivity in trapped electron regimes
Abstract
The distribution function is determined numerically for electrons subject to magnetic trapping, electronelectron, and electronion collisions, and an electric field large enough to invalidate the SpitzerHärm (classical) approximation. The electrical resistivity is determined. It is compared with analytical theory for tokamaks, in the limit of large inverse aspect ratio ɛ, and small drift velocity V_{d}/V_{th}. The resistivity is plotted for values of ɛ and V_{d}/V_{th} for which no analytic theory is available.
