| Abstract;The Beam Position Monitor(BPM) System for KEKB has been in use to measure closed orbit distortion since the start of commissioning in December 1998. The High Energy Ring(HER) and the Low Energy Ring(LER) for KEKB are each equipped with about 450BPMs. Most BPMs(-97%) were aligned in relation to their nearest quadrupole magnet(Qmag) to within 50.MU.m. The BPM system has been regularly operated to measure beam positions with a resolution of a few microns and at a sampling period of about four seconds. Oscillations of the beam orbits have also been measured by using other functions of this system. This report describes the performance of the system and results of operation. (author abst.) |
