Abstract

A new method using a streak camera to observe the synchrotron radiation of LEP was developed for the bunch measurement. This allowed monitoring of the particle density distribution in three dimensions in space at successive bunch passages. The optical set-up allows viewing of the top view and side view of the bunch simultaneously. The software analyzes the density distribution in these two perpendicular planes and extracts online the a and the center of gravity for the bunch length and also for transverse dimensions. We will give the experimental results of the resolution limits due to the streak camera in this application. The resulting influence of the transverse photon bunch dimension on the measured bunch length will be presented and compared with the calculation
