Keywords: | Liquid xenon; Dark matter | Issue Date: | 2005 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 551:2-3 (2005) 356-363 | Abstract: | Scintillation light produced in liquid xenon (LXe) by alpha particles, electrons and gamma-rays was detected with a large area avalanche photodiode (LAAPD) immersed in the liquid. The alpha scintillation yield was measured as a function of applied electric field. We estimate the quantum efficiency of the LAAPD to be 45%. The best energy resolution from the light measurement at zero electric field is 7.5%([sigma]) for 976 keV internal conversion electrons from 207Bi and 2.6%([sigma]) for 5.5 MeV alpha particles from 241Am. The detector used for these measurements was also operated as a gridded ionization chamber to measure the charge yield. We confirm that using a LAAPD in LXe does not introduce impurities which inhibit the drifting of free electrons. | URI: | https://hdl.handle.net/10316/4419 | DOI: | 10.1016/j.nima.2005.06.054 | Rights: | openAccess |
