    • 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 ...

    • Sheet beam emittance measurements by slit-pinhole method 

      Cheng, S.; Destler, William (Elsevier, 1996)
      A method for measuring sheet electron beam emittance is developed. The effective emittances are obtained through construction of particle distribution in the transverse dimensions using slit- pinhole parameters. Measurement ...
