Muon Flux Monitoring in the YerPhI Underground Laboratory

We have organized the muon flux monitoring in the YerPhI underground laboratory. Muon detector system consists of two pairs of plastic scintillators 50x50x5cm3size. The data acquisition system registered and stored 1-sec, 1-minute and 1-hour time series of the detector counts. Time series are transferred to the Cosmic Ray Division database via 1 km long cable and then radio-modems and are accessible on-line via ADEI multivariate visualization platform.
