• The theory of an r. f. plugging of a magnetically confined plasma in an open-ended system is presented; it takes explicit account of the collective effect brought about by the dynamic screening action of the plasma. The theory predicts a maximum efficiency of the r. f. plugging at an optimum frequency corresponding to a zero of the longitudinal dielectric constant. The plugging efficiency is calculated as a function of the plasma density, the strength of the r.f. field, and the intensity of the magnetic field. These theoretical predictions are compared with the experimental observations, demonstrating a satisfactory agreement in overall features. The results provide a useful scaling law associated with the concept of the r.f. confinement. The theory also offers an adequate explanation for the discrepancy between the experimental values of the optimum frequency and those predicted by a conventional theory based on an individual-particle model.
