Patent number: 8884519Abstract: Disclosed herein is a class of mm and sub mm wavelength amplifiers and oscillators operating with miniature helical slow wave circuits manufactured using micro fabrication technology. The helices are supported by diamond dielectric support rods. Diamond is the best possible thermal conductor, and it can be bonded to the helix. The electron beam is transmitted, not through the center of the helix, but around the outside. In some configurations the RF power produced may be radiated directly from the slow wave circuit. The method of fabrication, which is applicable above 60 GHz, is compatible with mass production.Type: GrantFiled: March 22, 2012Date of Patent: November 11, 2014Assignee: Manhattan Technologies Ltd.Inventors: James A. Dayton, Jr., Carol L. Kory

Publication number: 20100045160Abstract: This disclosure describes a multibeam doubly convergent electron gun. Two or more beamlets can be run parallel to the axis at a prescribed radius to produce sufficient current to drive the VED. In order to obtain sufficient cathode surface area to provide the required current, the beamlets are launched from a cathode radius greater than the radius required in a slow wave circuit. In one embodiment, an electron gun includes a focus electrode that surrounds two or more cathodes, wherein each cathode emits a beamlet comprised of a plurality of electrons directed to a predetermined location. A first anode receives each beamlet at the predetermined location, accelerates each beamlet and changes the radius of each beamlet. A second anode receives each beamlet from the first anode, directs each beamlet along a predetermined axis, further accelerates, and can further compress each beamlet.Type: ApplicationFiled: August 20, 2009Publication date: February 25, 2010Inventors: James A.

Patent number: 7071604Abstract: An electron gun (10) includes an electron multiplier (22, 22?, 22?, 110) has a receiving end (50, 50?, 50?) for receiving primary electrons and an output end (54, 54?, 54?) that emits secondary electrons responsive to primary electrons arriving at the receiving end. An electron emitter (20, 20?, 20?, 102) is arranged at the receiving end of the electron multiplier for supplying primary electrons thereto. At least one of an electrical and a magnetic focusing component (14, 16) is arranged at the open output end of the electron multiplier for focusing the secondary electrons to define an electron beam.
