Description

A bunch length monitor used for detecting two frequency components of a beam spectrum has been developed for the TRISTAN accumulation ring (AR). The principle, design and performance of the monitor are described. The monitor comprises a stripline electrode, a coaxial cable and two identical synchronous detectors. Calibration of the monitor was carried out using the natural bunch length at a low beam current. The bunch length was measured at an injection energy of 2.5 GeV by the monitor and a streak camera. The imaginary part of the longitudinal coupling impedance was estimated by the potential well bunch lengthening and synchrotron tune shift. (orig.)
