Abstract

We report time and band -resolved scintillation from α-particles in Ar/CF4 mixtures at a pressure of 9.5 bar. Our results show that %-level addition of CF4 enables strong wavelength-shifted scintillation in the visible range, with yields at the level of 1000 ph/MeV, scintillation decay times of 9–25 ns and formation times well below 10 ns. Such a performance is a priori sufficient for accurate time-tagging of MeV-particles, without the need to resort to a pure noble gas, thus opening an appealing technological path for next-generation time projection chambers.
