    • Design of high-average-power near-millimeter free electron laser oscillators using short-period wigglers and sheet electron beams 

      Booske, John; Radack, Daniel; Antonsen, Thomas; Bidwell, Steven; Carmel, Yuval; Destler, William; Freund, Henry; Granatsein, Victor; Latham, Peter; Levush, Baruch; Mayergoyz, Isaak; Serbeto, A.

      The design and feasibility of a I-MW continuous wave (CW) free electron laser (FEL) oscillator are reviewed. The proposed configuration will include a short-period (1" - I cm) planar wiggler. a sheet electron beam, a ...

    • Experimental studies of overmoded relativistic backward-wave oscillators 

      Abe, David; Carmel, Yuval; Miller, Susanne; Bromborsky, Alan; Levush, Baruch; Antonsen, Thomas Jr; Destler, William (Institute of Electrical and Electronics Engineers, 1998-06)
      Internal field-emission breakdown in the electrodynamic structures of high-power microwave (HPM) devices can seriously limit the device’s output power and pulse duration. Increasing the diameter of the electrodynamic ...

    • Free electron laser pumped by a powerful traveling electromagnetic wave 

      Kehs, R.; Carmel, Yuval; Granatstein, Victor; Destler, William (©1990 IEEE. Personal use of this material is permitted.

      A three-wave free-electron laser (FEL) was operated with a powerful 8.4-GHz electromagnetic “pump” wave replacing the usual magnetostatic wiggler. The presence of a uniform axial magnetic field B,, produced cyclotron-harmonic ...

    • High-power microwave generation by excitation of a plasma-filled rippled boundary resonator 

      Carmel, Yuval; Minami, K.; Lou, Weiran; Kehs, R.; Destler, William; Granatstein, Victor; Abe, D.; Rodgers, J. (©1990 IEEE. Personal use of this material is permitted.

      An experimental demonstration of a strong enhancement of the interaction efficiency in a high-power relativistic backward-wave oscillator when plasma is injected is presented. Controlled plasma injection enhances the ...

    • A Novel highly accurate synthetic technique for determination of the dispersive characteristics in periodic slow wave circuits 

      Guo, Hezhong; Carmel, Yuval; Lou, Weiran; Chen, Leemian; Rodgers, John; Abe, David; Bromborsky, A.; Destler, William; Granatstein, Victor (IEEE, 1992-11)
      A novel, highly accurate (0.1-0.5%) synthetic technique for determining the complete dispersive characteristics of electromagnetic modes in a spatially periodic structure is presented. It was successfully applied for ...
