PEP-II and BaBar Shutdown Begins TodayEarly this morning, the BaBar detector stopped taking data and PEP-II crews began powering down the rings for a three-month downtime. During the seven and a half month run, PEP-II delivered 90 inverse femtobarns of integrated luminosity, a measure of the number of particle collisions in a given period of time. In August, the machine began breaking certain PEP-II records, including the best 30 days ever for integrated luminosity (19.7 inverse femtobarns) and the best week (5.4 inverse femtobarns). Peak luminosity came within a few percent of the record from the previous run, but in the beginning, the machine did not perform as well as hoped for during Run 6.
