Abstract
A simple analytic model of the radiation‐dominated decay of a compact torus is presented. Several striking features of various experiments (finite lifetime, linear current decay, and insensitivity of the lifetime to density or stored magnetic energy) are explained by the model. A simple criterion is given for the maximum tolerable impurity density.Keywords
