| contents | We report time and band-resolved scintillation from $α$-particles in Ar/CF$_4$ mixtures at a pressure of 9.5 bar. Our results show that %-level addition of CF$_4$ 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. |
