The investigation into the longevity of gaseous detectors is of paramount importance, particularly in anticipation of the forthcoming upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC) and the planned alterations to the CMS forward endcap zone. Aging effects are meticulously examined at the Gamma Irradiation Facility (GIF++) at CERN, focusing on two crucial components: the ME1/1 and ME2/1 cathode strip chambers (CSC) within the CMS. These chambers, designed differently, serve as vital detectors in the CMS endcap muon rings situated in the forward region, where they operate under high background rates. Since its initiation in 2016, the irradiation process of the chambers has resulted in the accumulation of charge per unit length of anode wire exceeding 610 mC/cm for ME2/1 and 800 mC/cm for ME1/1, surpassing the expected charge accumulation at HL-LHC by more than threefold. The chambers were operated with an Ar + CO&sub(2) gas mixture containing varying fractions of 10%, 2%, and 5% CF&sub(4). No effects of CSC aging were detected throughout the observation period.
