Experimental results are presented on the passage of strong-current electron beam through a low-pressure gas. It is shown that gas focusing is observed at a pressure 0.4 — 1 Torr. Characteristic singularities of the beam structure are observed at 0.1 — 1 Torr. The experiments were performed at electron energies 300 and 700 keV.
