The BTeV Trigger System
- Fermilab
BTeV is a dedicated beauty and charm experiment proposed for the Fer- milab Tevatron. The broad physics program envisaged for BTeV requires a trigger that is efficient for a wide variety of heavy-quark decays, includ- ing those to all-hadronic final states. To achieve this, we plan to trigger on evidence of detached vertices at the very first trigger level, taking ad- vantage of fast-readout pixel detectors to facilitate fast pattern recognition. Simulations show that 100-to-1 rejection of light-quark background events can be achieved at Level 1 using specialized trackfinding hardware, and that an additional factor of 10 to 100 in data reduction can be achieved using general-purpose-processor farms at Levels 2 and 3. This is adequate to allow data-taking at luminosities in excess of 2 x 1032 cm-2s-1.
