Abstract

We describe the Level 1 muon trigger system for Run 2 of the DØ colliding beam experiment at the Fermilab Tevatron. The Level 1 muon trigger rate for high P_T single muons and low P_T dimuons is designed to be less than 25% of the 10 kHz total Level 1 trigger bandwidth at a peak luminosity of 2×10³²/cm ²/s. The muon trigger logic makes use of tracks from the central fiber tracker and hits from all muon detector elements. Details of event synchronization, event buffering, and FPGA trigger logic are given. Results on Gbit/s serial link transmission of data over coaxial cable are shown. Simulation of the muon trigger system is discussed
