Sumario:MSGC aging effects have been systematically studied to determine optimal performance in the design framework of the CMS forward tracker. Tests were conducted on prototypes under various operating conditions (glass substrates, Cr or Au strips, Ar-DME or Ne-DME gas mixtures, gas set-up purity, and others), using an X-ray generator for irradiation. The different steps of our investigations are summarized. They demonstrate the complexity of the aging phenomenon as well as the difficulty of getting stable behavior of MSGC detectors under high rates of irradiation.
