✦ Synopsis

This article contains a description of our effort to apply a recently developed tokamak disruption modeling code, DSTAR, to describe in some detail the dynamic evolution of a disrupting plasma in the TFTR experiment. The physical phenomena modeled in DSTAR, and two important new extensions of this model, those of hyper-resistivity and a plasma halo, are reviewed in this paper. We also present some data taken during one of the most rapid disruptions in TFTR and present the results of comparison of this data with predictions from the DSTAR code.
