M. Aguilarbenitez et al., STUDY OF MAGNETIC HELD EFFECTS IN DRIFT TUBES FOR THE BARREL MUON CHAMBERS OF THE CMS DETECTOR AT THE LHC, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 416(2-3), 1998, pp. 243-252
The drift chambers in the barrel region of the CMS detector are expose
d to magnetic stray fields. To study the performance of the muon recon
struction and the drift time-based muon trigger, prototypes were teste
d under the expected magnetic field conditions at the H2 test facility
at CERN. The results indicate that the overall chamber performance wi
ll not be affected. Only the bunch crossing identification capability
in the small region near eta = 1.1, corresponding to the border of the
solid angle region covered by the barrel, will be weakened. (C) 1998
