Radio-assay of Titanium samples for the LUX Experiment
D. S. Akerib, X. Bai, S. Bedikian +63
We report on the screening of samples of titanium metal for their radio-purity. The screening process described in this work led to the selection of materials used in the construct…
LUXSim: A Component-Centric Approach to Low-Background Simulations
D. S. Akerib, X. Bai, S. Bedikian +60
Geant4 has been used throughout the nuclear and high-energy physics community to simulate energy depositions in various detectors and materials. These simulations have mostly been…
Scintillation yield and time dependence from electronic and nuclear recoils in liquid neon
W. H. Lippincott, K. J. Coakley, D. Gastler +3
We have performed measurements of scintillation light in liquid neon, observing a signal yield in our detector as high as (3.5 0.4) photoelectrons/keV. We measure pulse shape…
After LUX: The LZ Program
D. C. Malling, D. S. Akerib, H. M. Araujo +71
The LZ program consists of two stages of direct dark matter searches using liquid Xe detectors. The first stage will be a 1.5-3 tonne detector, while the last stage will be a 20 to…
Scintillation and charge extraction from the tracks of energetic electrons in superfluid helium-4
W. Guo, M. Dufault, S. B. Cahn +3
An energetic electron passing through liquid helium causes ionization along its track. The ionized electrons quickly recombine with the resulting positive ions, which leads to the…
Data Acquisition and Readout System for the LUX Dark Matter Experiment
D. S. Akerib, X. Bai, S. Bedikian +60
LUX is a two-phase (liquid/gas) xenon time projection chamber designed to detect nuclear recoils from interactions with dark matter particles. Signals from the LUX detector are pro…
