Abstract :
First observation of liquid xenon scintillation due to α-particles and γ-rays with a large area avalanche photodiode immersed in the liquid is reported. An energy resolution of 10% (FWHM) and a coincidence time resolution of <1 ns (FWHM) were measured with 5.5 MeV α-particles and 511 keV γ-rays, respectively. The quantum efficiency of the photodiode for xenon scintillation light (λ=178 nm) is estimated to be ∼100%.
