Abstract

We report about experimental evidences of infrared scintillation in gaseous, liquid and crystal samples. We firstly studied noble gases at room temperature and near atmospheric pressure in the wavelength range between 0.7 and 1.81 mum. Ar gas emits infrared photons when irradiated by a proton beam. Ionization electrons also induce such emission when they drift in the medium. The spectrum shows sharp lines corresponding to transitions between atomic excited states. Also Xe gas scintillates in the infrared region with a quantum yield higher than 2.10(4) photons/MeV. Protons induce infrared scintillation in liquid Ar and liquid Xe too. We irradiated many inorganic crystals and studied their infrared emission between 1 and 15 mum. Some samplespresent significant infrared scintillation. Among them CsI(T1) has the highest yield ((4.9+/-0.3).10(3) photons/MeV restricted to 0.7 divided by1.8 mum), The spectrum shows a broad line centered around 1.55 mum.
