  • Patent number: 5973289
    Abstract: A microwave-driven plasma spraying apparatus can be utilized for uniform high-powered spraying. The plasma sprayer is constructed without a dielectric discharge tube, so very high microwave powers can be utilized. Moreover, the plasma sprayer is relatively free of contamination caused by deposits of heat-fusible material.
    Type: Grant
    Filed: February 17, 1998
    Date of Patent: October 26, 1999
    Assignee: Physical Sciences, Inc.

  • Patent number: 4661783
    Abstract: Free-electron lasers and masers are modified by eliminating the resonator cavity as such. The feedback mechanism, essential to oscillation, is distributed through and integrated with the transmission line which guides the electromagnetic wave at the active region where interaction with the electron beam takes place. The feedback structure is created by perturbations in the transmission line along the length thereof at the locations of the zero electric field lines of a desired oscillatory standing wave mode. The perturbations may take the form of axial, helical, and azimuthal deformation of the transmission line.

  • Patent number: 4554484
    Abstract: A complex cavity gyrotron designed for stable operation at high order modes. The device comprises circuitry for generating an annular electron beam, a coupled cavity disposed coaxially with the electron beam and having a first and second adjacent coaxial sections with the dimensions of these coaxial sections adjusted so that different modes with the same azimuthal eigen number but different radial eigen numbers are simultaneously resonant at approximately the same frequency in the two sections, and circuitry for generating an axial magnetic field within the cavity. Few, if any, combinations of modes other than the combination chosen will simultaneously resonate in the cavity thereby effecting higher order mode suppression. The present design has a low susceptibility to beam velocity spread and is effective for any combination of modes with identical azimuthal eigen numbers.
