    • Millimeter wave free electron laser amplifiers: Experiments and designs 

      Bidwell, S.; Zhang, Z.; Antonsen, T. Jr; Bensen, D.; Destler, William; Freund, H.; Granatstein, V.; Latham, P.; Levush, B.; Radack, D.; Rodgers, J. (1991-08)
      Free electron laser amplifiers are investigated as sources of high average-power (1 MW) millimeter to submillimeter wave radiation (200-600 GHz) for application to electron cyclotron resonance heating of magnetically ...

    • Novel method for determining the elctromagnetic dispersion relation of periodic slow wave structures 

      Carmel, Y.; Guo, H.; Lou, R.; Abe, D.; Granatstein, V.; Destler, William (©1990 American Institute of Physics, 1990-09-24)
      A novel method for calculating the dispersion relation of electromagnetic modes in an arbitrary periodic slow wave structure is reported. In this method it is sufficient to know the frequencies corresponding to three special ...

    • Observation of a resonant enhancement of microwave radiation from a gas-filled backward wave oscillator 

      Minami, K.; Lou, W.; Destler, William; Kehs, R.; Granatstein, V.; Carmel, Y. (American Institute of Physics, 1988-08-15)
      High-power microwave radiation at 8 GHz from a gas-fined backward wave oscillator driven by an intense relativistic electron beam has been measured. It has been observed that an order of magnitude resonant increase in ...

    • Periodic magnetic focusing of sheet electron beams 

      Booske, J.; Basten, M.; Kumbasar, A.; Antonsen, T.; Bidwell, S.; Carmel, Y.; Destler, William; Granatstein, V.; Radack, D. (American Institute of Physics, 1994-05)
      Sheet electron beams focused by periodically cusped magnetic (PCM ) fields are stable against low-frequency velocity-shear instabilities (such as the diocotron mode). This is in contrast to the more familiar unstable ...

    • Progress in high power millimeter-wave FELs with short period wigglers and sheet electron beams 

      Booske, J.; Radack, D.; Antonsen, T. Jr; Bidwell, S.; Destler, William; Granatstein, V.; Latham, P.; Levush, B.; Mayergoyz, L.; Serbeto, A.; Zhang, Z. (Institute of Electrical and Electronics Engineers, 1989-05)

    • Propagation of wiggler focused relativistic sheet electron beams 

      Booske, J.; Destler, William; Segalov, Z.; Radack, D.; Rosenbury, E.; Rodgers, J.; Antonsen, T.; Granatstein, V.; Mayergoyz, I. (American Institute of Physics, 1988-02-09)
      A recent design concept for millimeter-wave free-electron lasers [J. Appl, Phys, 60, 521 ( 1986)] would require the stable propagation of a sheet electron beam through a narrow waveguide channel. Experimental results ...

      Levush, B.; Antonsen, T. Jr; Bromborsky, A.; Lou, W.; Abe, D.; Miller, S.; Carmel, Y.; Rodgers, J.; Granatstein, V.; Destler, William (IEEE, 1991)
      Microwave sources based on backward-wave oscillators with relativistic electron beams are capable of producing high power coherent radiation in the cm and mm wavelength regime. Although there have been a number of ...
