A high P T muon trigger processor
1991
A high P/sub T/ muon trigger has been designed and built for application in E771, an 800 GeV experiment on beauty hadrons at Fermilab. The trigger processor uses two-dimensional pad chamber signals to identify straight line trajectories downstream of a single analyzing magnet. The trigger processor works at an interaction rate higher than 10/sup 7/ Hz with a short processing time of about 150 ns. The P/sub T/ threshold is selectable and variable from 0.6 GeV/c to more than 1 GeV/c. It takes about 6000 input signals from three to four detector planes to recognize 40000 high P/sub T/ patterns out of several million possible combinations. The background rejection in the initial test run, using only the larger y-angle region, ranged from 10 to 30. >
