The BABAR detector: Upgrades, operation and performance
The BaBar detector operated successfully at the PEP-II asymmetric e^+e^− collider at the SLAC National Accelerator Laboratory from 1999 to 2008. This report covers upgrades, operation, and performance of the collider and the detector systems, as well as the trigger, online and offline computing, and aspects of event reconstruction since the beginning of data taking.

The authors are grateful for the tremendous support they have received from their home institutions over the almost 10 years of BaBar and PEP-II operation. The excellent performance of PEP-II, the data taking, the data processing and the data analysis would not have been possible without the extraordinary expertise, dedication and collaboration of the supporting staff at SLAC and other BaBar institutions, as well as at participating computing centers. The collaborating institutions wish to thank SLAC for the kind hospitality extended to them. Members of the International Finance Committee should be commended for their continued assistance in securing resources for the operation and upgrades of the experiment.
