A model is proposed which links electron beam propagation through plasma into a vacuum with collective ion acceleration from the plasma. Electron reflection from the virtual cathode at the beam front transfers momentum to the ions, and a moving ion channel is formed allowing the electron beam to propagate. A momentum‐balance equation is derived, and theoretical results for the ion velocity are in good agreement with the experimental data. Conditions for transverse beam confinement are discussed.
