To exploit the PEP-II facility, a new detector has been built by a
large international collaboration of physicists. The detector is called
BaBar, which refers to the B/B-bar system of mesons produced at SLAC's
PEP-II collider. The BaBar detector consists
of a silicon vertex detector, a drift chamber, a particle
identification system, a CsI electromagnetic calorimeter, and a magnet
with an instrumented flux return. The detector operations
gives up-to-date information on the running of the detector.
