    • 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 ...

    • Experimental realization of millimeter-wave amplification by a sheet beam free electron laser 

      Zhang, Ze-Xiang; Destler, William; Granatstein, V.; Antonsen, T.; Levush, B.; Rodgers, J.; Cheng, S. (American Institute of Physics, 1994-03-14)
      We report an observation of millimeter-wave (94 GHz) amplification in a sheet beam, short period, planar wiggler: free electron laser amplifier. The observed gain is about 5 dB for a 530 keV, 4 A beam through a 54 cm ...

    • First operation of a 94 GHz, sheet beam, FEL amplifier 

      Zhang, Ze-Xiang; Granatstein, V.; Destler, William; Levush, B.; Antonsen, T.; Rodgers, J.; Cheng, S. (Elsevier, 2002-10-14)
      Millimeter wave (94 GHz) amplification has been observed in the sheet beam, planar wiggler, free electron laser. Using a 4 A sheet beam (20 mm × 1.0 mm) at an electron energy of 530 keV, injected wave power of 5 W was ...
