Descripción
Massive liquid Ar detectors are being built for the next generation of dark matter searches and neutrino physics. All these detectors exploit the scintillation light of Ar, which is usually assumed to be purely at 128 nm. Our spectral time-resolved analysis of the argon scintillation light revealed a substantial component in the 160 to 300 nm range, which is the dominant prompt emission with alpha particles in gas at 1 bar. We have developed several chambers to characterize the spectral emission of Ar in the conditions of dual phase TPCs. This investigation opens the path to exploiting the spectroscopic features of the Ar-light emission for the ultimate generation of direct dark-matter detectors.
