    "abstract": "Scintillation light produced in liquid xenon (LXe) by alpha particles,\nelectrons and gamma-rays was detected with a large area avalanche photodiode\n(LAAPD) immersed in the liquid. The alpha scintillation yield was measured as a\nfunction of applied electric field. We estimate the quantum efficiency of the\nLAAPD to be 45%. The best energy resolution from the light measurement at zero\nelectric field is 7.5%(sigma) for 976 keV internal conversion electrons from\nBi-207 and 2.6%(sigma) for 5.5 MeV alpha particles from Am-241. The detector\nused for these measurements was also operated as a gridded ionization chamber\nto measure the charge yield. We confirm that using a LAAPD in LXe does not\nintroduce impurities which inhibit the drifting of free electrons.",
