The CMS muon system

Same sign dimuon search for heavy majorana mass neutrinos at the CMS experiment at CERN and design studies of a quartz plate calorimeter prototype

“…The CMS DTs are rectangular tubes two to three meters long filled with an Ar/CO 2 gas mixture. A schematic is shown in Figure 2.7 [26]. Running down the center of each tube is an anode wire maintained at 3.7 kV voltage.…”
