M. Andlinger et al., PATTERN COMPARATOR TRIGGER (PACT) FOR THE MUON SYSTEM OF THE CMS EXPERIMENT, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 370(2-3), 1996, pp. 389-395
The general scheme for the fast, pipelined first level trigger on high
p(t) muons in the CMS detector at LHC is presented. The prototype PAC
T system was tested in the high momentum muon beams in the RD5 experim
ent during 1993/94 runs. The obtained efficiency curves are shown.
