Abstract
First observation of liquid xenon scintillation due to α-particles and γ-rays with a large area avalanche photodiode is reported. Energy resolution of 10% (fwhm) and coincidence time resolution of 0.9 ns (fwhm) were measured with 5.5 MeV α-particles and 511 keV γ-rays, respectively. Quantum efficiency of the photodiode for xenon scintillation light (178 nm) is estimated to be ~100%
