  A test of the lifetime of an amorphous carbon foil of ~79 ug/cm2 was performed at PSI in the transfer line between Injector 2 and Ring cyclotron during the regularly beam production. The 72 MeV ~1.7 mA proton beam had a central current density of ~2.8 mA/cm2. Two spots on the foil were irradiated alternatively with in total three fractions of 17, 52 and 119 mAh. Foil thickness was measured before and after irradiation at several positions via the energy loss of alpha-particles from a 241Am source in the foil. We discuss the observed foil damage as well as the experimental setup, the estimation of the beam parameters and practical boundary conditions.
