The BaBar Level 1 Drift-Chamber Trigger Upgrade With 3D Tracking
Conference
·
OSTI ID:878055
At BABAR, the Level 1 Drift Chamber trigger is being upgraded to reduce increasing background rates while the PEP-II luminosity keeps improving. This upgrade uses the drift time information and stereo wires in the drift chamber to perform a 3D track reconstruction that effectively rejects background events spread out along the beam line.
