Expressions for the potential difference Phi/sub p/b between the plug and barrier regions of a tandem-mirror thermal barrier cell are derived in the limit of strong electron-cyclotron heating. It is found that Phi/sub p/b varies as the 2/3 power of the ratio of the density of electrostatically trapped plug electrons to the density of thermal electrons at the barrier. Electric-field requirements for validity of the solutions are presented.
