Abstract: A klystron tube for amplifying signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field focused by a high energy magnet in the RF section of the tube. After the electrons have passed through the active area of the tube, the electrons strike the collector which, in this case, is a multistage depressed collector. The multistages of the depressed collector are connected to high energy voltage sources of different potentials. The klystron tube with the multistage depressed collector is uniquely used here for the first time in a ground based satellite or terrestrial communications system.

Abstract: An electron beam generating section of an electron gun assembly includes at least a cathode that emits an electron beam, and a control electrode that is disposed on a phosphor screen side of the cathode. The cathode has a cathode face that is opposed to the control electrode, the cathode face having a concave shape with a recessed central portion. The electron beam that is emitted from the cathode face forms a cross-over with a tube axis. A cross-over point of an electron beam, which is emitted from the central portion of the cathode face, differs from a cross-over point of an electron beam, which is emitted from an off-axis portion of the cathode face.

Abstract: A magnetic field source that produces a stepped field of greater magnitude than the remanence of the magnetic material used to construct it. The source is basically a magnetic igloo comprised of two hemispheres having different cavity flux value that are separated by a passive ferromagnet slab. The hemispheres are positioned such that they share the same radial center point. The slab has a predetermined thickness and a tunnel of predetermined radius passing through its center along the radial center point of said hemispheres such that the flux in the cavity of the hemisphere abruptly changes when passing from the first hemisphere flux to the second.
