Primary scintillation yields induced by $\alpha$ particles in gas
mixtures of Argon/CF$_4$ at 9.5 bar
We report time and band-resolved scintillation from $\alpha$-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 …
