Measurements of longitudinal phase space in the SLC linac

The electron and positron bunch distributions in the Stanford Linear Collider (SLC) linac have been measured using a Hamamatsu, model N3373-02, 500-femtosecond streak camera. The distributions were measured at the end of the SLC linac versus the bunch compressor RF voltage. The energy spread at the end of the linac was also measured using a wire scanner. The effects of the bunch compressor on the shape of the bunch distribution are also presented.
