Streak camera measurements of the longitudinal distribution of a single bunch in CESR

Measurements of the beam's bunch length in the Cornell Electron-Positron Storage Ring (CESR) were made using a streak camera. The experimental set up and the analysis techniques used are described in this paper. For a single bunch in CESR, the dependence of the longitudinal distribution on the bunch current and accelerating RF voltage, was measured and compared with a simple theoretical model of the CESR vacuum chamber impedance. Some basic parameters of this model were determined from the measured bunch distributions presented in this paper.
