Title: Triggering BTeV
Abstract: BTeV is a collider experiment at Fermilab designed for precision studiesof CP violation and mixing. Unlike most collider experiments, the BTeVdetector has a forward geometry that is optimized for the measurement of Band charm decays in a high-rate environment. While the rate of B productiongives BTeV an advantage of almost four orders of magnitude over e+e-B factories, the BTeV Level 1 trigger must be able to accept data at a rateof 100 Gigabytes per second, reconstruct tracks and vertices, trigger on Bevents with high efficiency, and reject minimum bias events by a factor of100:1. An overview of the Level 1 trigger will be presented.
