    • Experimental and numerical studies of sheet electron beam propagation through a planar wiggler magnet 

      Zhang, Ze-Xiang; Granatstein, Victor; Destler, William; Bidwell, Steven; Rodgers, J.; Cheng, S.; Antonsen, T.; Levush, B.; Radack, D. (IEEE, 1993-12)
      Detailed experimental studies on sheet relativistic electron beam propagation through a long planar wiggler are reported and compared with numerical simulations. The planar wiggler has 56 periods with a period of 9.6 ...

    • Free electron laser pumped by a powerful traveling electromagnetic wave

      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 ...

    • Free electron laser with small period wiggler and sheet electron beam: A Study of the feasibility of operation at 300 GHz with 1 MW CW output power 

      Booske, J.; Granatstein, Victor; Antonsen, T.; Destler, William; Finn, J.; Latham, P.; Levush, B.; Mayergoyz, I.; Radack, D.; Rodgers, J. (1989)
      The use of a small period wiggler (Cw < 1 cm) together with a sheet electron beam has been proposed as a low cost source of power for electron cyclotron resonance heating (ECRH) in magnetic fusion plasmas. Other potential ...

    • 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 High-power millimeter-wave sheet beam free-electron laser amplifier 

      Cheng, Shiqiu; Destler, William; Granatstein, Victor; Antonsen, Thomas; Levush, Baruch; Rodgers, John; Zhang, Z. (©1996 IEEE. Personal use of this material is permitted.

      The results of experiments with a short period (9.6 mm) wiggler sheet electron beam (1.0 mm x 2.0 cm) millimeter-wave free electron laser (FEL) amplifier are presented. This FEL amplifier utilized a strong wiggler field ...

    • 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 ...
