Experimental studies are presented on the propagation of an intense, pulsed proton beam (890 kV, 50 ns) through a z‐discharged plasma channel (50 cm long, 1.1 to 10 Torr, air) in the presence of return channels (30 cm long). From the measurements by an image converter camera and a small‐sized magnetic probe, we have found the compression (deformation) of the main channel due to the presence of the return channels. Enhancement of the beam power density has also been observed. Good efficiency of the propagation (approximately 33%) has been observed through the main channel. © 2001 Scripta Technica, Electr Eng Jpn, 136(4): 1–6, 2001
