New Luminosity Record for PEP-II

(Graph - PEP II luminosity)


The plot shows the PEP-II record period, broken up into the three contributing shifts. The red line represents the PEP-II luminosity, while the green and blue lines are the currents in the low-energy and high-energy rings, respectively. The yellow blocks show the time BaBar was live and recording data, with the vertical black lines representing the change of run occurring approximately every 52 minutes.
