Abstract :
Small Gap+GEM Chambers developed for the CMS experiment at the LHC were exposed to a pion beam of 350 MeV at the Paul Scherrer Institut to establish their radiation hardness with respect to the operating gain. The long-term stability of the gain (ageing) was then measured using an X-ray beam.
