Bunch length measurement using beam spectrum

  • 1. Cornell Univ., Ithaca, NY (United States)

Description

A procedure for extracting the bunch length from the beam induced voltage spectrum is applied at CESR, for various bunch currents, to indicate whether the turbulent lengthening threshold is exceeded by short, high-current bunches. The approach is to monitor the signal spectrum from one of the detector buttons up to 8 GHz. The measuring system is calibrated by reference to a low-current bunch (1 mA), which is assumed to have a gaussian profile with the theoretically predicted length. In this experiment a single bunch was used with a natural length of 15 mm. No bunch lengthening was detected up to a current of 20 mA
