Abstract : A quasi-steady state solution was obtained for a homogenous plasma undergoing simultaneous ionization and rotation in a crossed electricmagnetic field. It was found that the ordinary electron-impact ionization process, when supported by the Landau ion-electron heat transfer mechanism, will be sufficiently rapid to provide a close coupling between the kinetic energy of the ions and the ionization energy of the neutrals under a wide range of conditions. The results can be used to interpret the limiting velocity observed by Alfven (Rev. Mod. Phys. 32:710 (1960)) and Fahleson (Phys. of Fluids 4:123 (1961)) in some recent rotating plasma experiments. The same results can also be used to predict the occurrence of similar limiting velocity in some rectilinear plasma accelerators. (Author)
