Muon chambers of Argus detector

This paper describes a new universal ARGUS detector created to study e+e- interactions on the DORIS-II collider. The detector consists of a central drift chamber, time-of-flight counters, and an electromagnetic calorimeter. The detector is enclosed on all sides by three layers of muon counters for registration of muons. The entire system of muon chambers of the ARGUS detector has operated stably from October 1982 until today. The background loads of the muon chambers during an experiment are not great. The average number of signals in the chambers is 0.98 per start-up. The operation of the muon chambers has been constantly monitored according to the counting response of the tubes for cosmic particles, and the quality of the gas has been monitored by comparing the positions of the peaks from Fe 55 radioactive sources in test proportional counters at the inlet and outlet of the gas channel
