Abstract

Measurements of the longitudinal pulse length of femtosecond electron beams have been performed by the three methodologies at the 35 MeV S-band twin linear accelerators at the Nuclear Engineering Research Laboratory, University of Tokyo. The methods we adopt are a femtosecond streak camera with dispersionless reflective optics, the coherent transition radiation (CTR) Michelson interferometer and the CTR polychromator. The results were compared with one another and the reliabilities of the methods to diagnose femtosecond electron pulses have been discussed
