Neutrino physics with multi-ton scale liquid xenon detectors
We study the sensitivity of large-scale xenon detectors to low-energy solar neutrinos, to coherent neutrino-nucleus scattering and to neutrinoless double beta decay. As a concrete example, we consider the xenon part of the proposed DARWIN (Dark Matter WIMP Search with Noble Liquids) experiment. We perform detailed Monte Carlo simulations of the expected backgrounds, considering realistic energy...
متن کاملNeutron background in large-scale xenon detectors for dark matter searches
Simulations of the neutron background for future large-scale particle dark matter detectors are presented. Neutrons were generated in rock and detector elements via spontaneous fission and (α,n) reactions, and by cosmic-ray muons. The simulation techniques and results are discussed in the context of the expected sensitivity of a generic liquid xenon dark matter detector. Methods of neutron back...
متن کاملIntercomparison of retrospective radon detectors.
We performed both a laboratory and a field intercomparison of two novel glass-based retrospective radon detectors previously used in major radon case-control studies performed in Missouri and Iowa. The new detectors estimate retrospective residential radon exposure from the accumulation of a long-lived radon decay product, (210)Pb, in glass. The detectors use track registration material in dire...
متن کاملMeasuring Reflective Properties of PTFE for Applications in Liquid Xenon Detectors
The XENON100 experiment uses 161kg of liquid xenon divided in two concentric cylinders. The inner volume is the time-projection chamber, the outer volume is the veto, and they are separated by PTFE (Teflon) panels. In the region 350nm to 1200nm, PTFE has a measured reflectivity of 99%. However, xenon emits in the UV region, and the reflectivity distribution is not sufficiently understood here. ...
متن کامل1 “ Liquid Xenon R & D for Future Large - Scale Dark - Matter Detectors ”
A strong theoretical candidate for weakly interacting massive particles (WIMPs) is the neutralino. The neutralino is the lightest supersymmetric particle (LSP), from supersymmetry (SUSY) theory, that would be formed in the early universe and subsequently cluster in galaxies with normal matter. This could account for the ~90% non-luminous mass inferred in our Galaxy from the motion of stars and ...
