Axisymmetric scrape-off plasma transport

Research output: Contribution to journalArticlepeer-review


The two-dimensional flow of a collision-dominated hydrogen scrape-off plasma in an axisymmetric tokamak is examined. This flow is described by a set of equations which contain the dominant terms in a maximal ordering appropriate to high-density experimental divertors and reactor scrape-off plasmas. Comparison of the theory to estimates of scrape-off parameters in the Doublet III expanded boundary plasmas suggests that analysis of classical and neoclassical processes alone may be sufficient to predict plasma transport in high-density scrape-off plasmas of practical importance.
