BaBar Detector
Building
on the original 2200-meter
PEP storage ring and in cooperation with LBNL and LLNL,
SLAC constructed an extensive upgrade called the
B Factory which is producing millions of B mesons.
This upgrade includes modifications to the PEP storage ring
and a new type of detector, called
BaBar.
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 B Factory includes a second ring of magnets and other devices to increase the particle collision rate 50 times more than the original facility. This high collision rate is necessary for the study of the matter-antimatter asymmetry. |
