Atomic limits in the search for galactic dark matter
Peter Sorensen
Direct searches for low mass dark matter particles via scattering off target nuclei require detection of recoiling atoms with energies of ~1 keV or less. The amount of electronic e…
Low-Energy (<10 keV) Electron Ionization and Recombination Model for a Liquid Argon Detector
Michael Foxe, Chris Hagmann, Igor Jovanovic +6
Detailed understanding of the ionization process in noble liquid detectors is important for their use in applications such as the search for dark matter and coherent elastic neutri…
Radiogenic and Muon-Induced Backgrounds in the LUX Dark Matter Detector
D. S. Akerib, H. M. Araujo, X. Bai +77
The Large Underground Xenon (LUX) dark matter experiment aims to detect rare low-energy interactions from Weakly Interacting Massive Particles (WIMPs). The radiogenic backgrounds i…
Design and demonstration of a quasi-monoenergetic neutron source
T. H. Joshi, S. Sangiorgio, V. Mozin +5
The design of a neutron source capable of producing 24 and 70 keV neutron beams with narrow energy spread is presented. The source exploits near-threshold kinematics of the L…
A Detailed Look at the First Results from the Large Underground Xenon (LUX) Dark Matter Experiment
M. Szydagis, D. S. Akerib, H. M. Araujo +77
LUX, the world's largest dual-phase xenon time-projection chamber, with a fiducial target mass of 118 kg and 10,091 kg-days of exposure thus far, is currently the most sensitive di…
First measurement of the ionization yield of nuclear recoils in liquid argon
T. H. Joshi, S. Sangiorgio, A. Bernstein +9
This Letter details a measurement of the ionization yield () of 6.7 keV atoms stopping in a liquid argon detector. The of 3.6-6.3 detected $e^{-}/\mbox{keV}$,…
