Abstract

Structural change in polyethylene naphthalate (PEN) foil during MeV proton beam irradiation was investigated by ion beam induced luminescence (IBIL). An aluminum thin film (thickness: 20 nm) was sputter-deposited on the upper surface of 4 μm thick PEN foil to evaluate how Al coating effects structural change. IBIL analysis reveals that the Al coating clearly reduces damage induced by ion beam irradiation, probably due to the enhancement of electrical conductivity of the foil.
