We present the results of an upgrade to the D0 muon system. Scintillating counters have been added to the existing central D0 muon system to provide rejection for cosmic ray muons and out-of-time background, and to provide additional fast timing information for muons in an upgraded Tevatron. Performance and results from the 1994-1996 Tevatron run are presented.We present the results of an upgrade to the DO muon system.

Abstract The high luminosity environment of the upgraded Tevatron will require not only the upgrade of various DO subdetectors, but the trigger system as well. With respect to the present system, the upgraded trigger system must operate faster and provide a higher degree of background rejection while extending the physics acceptance beyond that of the current system. This will be accomplished in part by incorporating the scintillating fiber tracker and the preshower detector into the Level 1 trigger. Track logic, implemented in commercial FPGAs, will be used to identify tracks in the scintillating fiber tracker with P T >1.5 GeV/ c and electron candidates in the preshower detector. Integration of the trigger logic and readout electronics permits the identification of all tracks in a few hundred nanoseconds. Here, preliminary designs for the readout and trigger electronics are presented along with simulation results for trigger efficiencies and rejection factors.
