The BTeV trigger—recent developments

BTeV is a collider experiment at the Fermilab Tevatron dedicated to precision measurements of CP violation, mixing and rare decays of beauty and charm hadrons. The detector is a forward spectrometer with a pixel vertex detector inside a dipole magnet. A unique feature of BTeV is the trigger, which reconstructs tracks and vertices in every beam crossing. We present here an overview of the BTeV trigger and a description of recent improvements in trigger timing.
