Abstract: An electron gun emits a steady stream of electrons. The electrons pass to a modulating cavity which accelerates some of the electrons and decelerates other electrons in a particular timed relationship so that the electrons become periodically bunched. The bunched electrons are then accelerated in an accelerator to a constant speed such as the speed of light to maintain the bunching of the electrons and to substantially increase the energy of the electrons. The kinetic energy in the bunches of electrons is then converted to microwave energy. The conversion may occur in one output cavity or in a series of output cavities. Apparatus such as described above may be connected in parallel to further increase the output microwave energy.

Abstract: An electron gun for generating an electron beam is provided, which includes a secondary emitter. The secondary emitter includes a non-contaminating negative-electron-affinity (NEA) material and emitting surface. The gun includes an accelerating region which accelerates the secondaries from the emitting surface. The secondaries are emitted in response to a primary beam generated external to the accelerating region. The accelerating region may include a superconducting radio frequency (RF) cavity, and the gun may be operated in a continuous wave (CW) mode. The secondary emitter includes hydrogenated diamond. A uniform electrically conductive layer is superposed on the emitter to replenish the extracted current, preventing charging of the emitter. An encapsulated secondary emission enhanced cathode device, useful in a superconducting RF cavity, includes a housing for maintaining vacuum, a cathode, e.g., a photocathode, and the non-contaminating NEA secondary emitter with the uniform electrically conductive layer superposed thereon.

Abstract: An amplifier including an electronic tube with an axial electron beam, provided with a cathode and at least two collectors, and at least two sources of DC voltage. Each collector is connected to a DC voltage source having a potential difference such that, the further the collector is from the cathode, the lower the potential difference between this collector and the cathode. The DC voltage sources are connected together at a common point situated at the collector whose potential difference with the cathode is the lower but not zero.

Abstract: An electron beam tube device such as an inductive output tube of the integral cavity type has a RF window which re-enters the interaction space within the cavity thereby defining a space that is within the interaction cavity but is outside the vacuum. An output coupler in the form of an output coupling loop protrudes into this space and thus couples with the electromagnetic field within the interaction space, whilst remaining outside the vacuum envelope. This allows the coupling loop to be adjusted without any additional seal arrangement between the coupling loop and walls of the output cavity.

Abstract: An electron beam tube device has a magnetic frame with the top part being pivotable so as to pivot from a closed position in which the top part, including an electromagnetic coil covers the electron beam tube to an open position in which the electron beam tube is uncovered. This allows electron beam tubes with either large parts or integral parts such as output feeders to be removed from the magnetic frame without complete removal of the top plate.
