Scintillation efficiency of liquid argon in low energy neutron-argon scattering (1504.07878v2)
Published 29 Apr 2015 in physics.ins-det, astro-ph.IM, and hep-ph
Abstract: Experiments searching for weak interacting massive particles with noble gases such as liquid argon require very low detection thresholds for nuclear recoils. A determination of the scintillation efficiency is crucial to quantify the response of the detector at low energy. We report the results obtained with a small liquid argon cell using a monoenergetic neutron beam produced by a deuterium-deuterium fusion source. The light yield relative to electrons was measured for six argon recoil energies between 11 and 120 keV at zero electric drift field.
