  • Abstract
    PEP-II is an asymmetric e+-e- collider operating at the Upsi(4S) energy and has recently set several performance records. The luminosity has reached a peak of 1.2 x 1034 cm-2 s-1. Operating in continuous injection mode for both beams PEP-II has delivered up to 0.91 fb-1 day-1. Peak currents have reached 3.0 A of positrons and 1.9 A of electrons in 1732 bunches. Total delivered luminosity since turn-on in 1999 has exceeded 450 fb-1. This paper reviews the present performance issues of PEP-II and also the planned increase of luminosity in the near future to 2 times 1034 cm-2 s-1.
