A high P/sub T/ muon trigger processor

High P/sub T/ provide an important means of identifying heavy-quark events in hadroproduction experiments. A fast high P/sub T/ muon trigger processor has been designed, built, and tested for application in E771, an 800-GeV experiment on beauty hadrons at Fermilab. The trigger processor used two-dimensional pad chamber signals to identify straight-line trajectories downstream of a single analyzing magnet. High P/sub T/ muons have trajectories with relatively little deviation by the magnet. These were made to give a trigger, with a processing time of about 150 ns. >
