Monitoring and Control System of the ATLAS RPCs in view of Run-2

Sumario:Resistive Plate Chambers provide the barrel region of the ATLAS detector with an independent muon trigger and a two-coordinate measurement. The chambers, 3600 gas volumes in total covering a surface area of about 4000 m2, are arranged in three concentric double layers and operated in a strong magnetic toroidal field. During Run-1 the LHC has provided proton-proton collisions at 7 and 8 TeV in the centre-of-mass frame with a steady increase in instantaneous luminosity, summing up to about 30 fb^-1. For Run-2 a further increase in beam energy, luminosity and also backgrounds is expected with rates and doses approaching the limits for which the RPCs were certified to work at irradiation facilities. In this scenario a precise and granular monitoring of the detector (gas gap currents, gas flow, trigger rates) along with a safe operation will become even more important. The operational experience from Run-1 and the present plans of upgrade and consolidation are presented along with a discussion from the point of view of the Detector Monitoring and Control System.
