Abstract :
We describe a simple method of measuring the total Higher Order Mode (HOM) losses and the synchrotron radiation losses in a storage ring based on a straightforward model of a beam - cavity interaction and a precise knowledge of the rf power distribution. This method works well at higher currents. The comparison of the measured HOM losses and the estimates is given for both Low Energy Ring (LER) and High Energy Ring (HER) rings of the PEP-II SLAC B-factory.
