Abstract
We describe the Level 1 muon trigger system for Run II of the [Formula: see text] colliding beam experiment at the Fermilab Tevatron. The muon trigger logic makes use of tracks from the central fiber tracker and hits from muon detector elements which include both scintillator and drift tube arrays. Details of the FPGA trigger logic and trigger simulation results are given. Extensive use is made of Gbit/s serial links in order to transmit data to the Level 1 muon trigger system. Results on error rates from these Gbit/s serial links using up to 200 feet of coaxial cable are presented.
