    "abstract": "The preliminary results of an aging test performed at the CERN Gamma\nIrradiation Facility on a single--gap RPC prototype developed for the LHCb Muon\nSystem are presented. The results are based on an accumulated charge density of\n0.42 C/cm^2, corresponding to about 4 years of LHCb running at the highest\nbackground rate. We observe a rise in the dark current and noise measured with\nsource off. The current drawn with source on steadily decreased, possibly\nindicating an increase of resistivity of the chamber plates. The performance of\nthe chamber, studied with a muon beam under several photon flux values, is\nfound to still fulfill the LHCb operation requirements.",
