An inductive output tube (IOT) of a multi-staged depressed collector provides improved efficiency by approximating a Brillouin electron beam flow. In one embodiment, an IOT is provided with an electron gun that generates an electron beam, a tube body, a multi-staged depressed collector for collecting the electron beam, and a magnetic solenoid. The electron beam travels through the tube body. The magnetic solenoid produces a magnetic flux that focuses the electron beam as it travels through the tube body. The magnetic flux includes a portion that threads through the electron gun. The IOT is adapted to reduce this portion of the magnetic flux in order to provide improvements in the efficiency of the IOT.
