The EXO-200 detector, part II: Auxiliary Systems
N. Ackerman, J. Albert, M. Auger +157
The EXO-200 experiment searched for neutrinoless double-beta decay of Xe with a single-phase liquid xenon detector. It used an active mass of 110 kg of 80.6%-enriched liqui…
GEANT4 models of HPGe detectors for radioassay
R. H. M. Tsang, A. Piepke, D. J. Auty +7
Radiation transport models of two high purity germanium detectors, GeII and GeIII, located at the University of Alabama have been created in GEANT4 \cite{geant4}. These detectors h…
Characterization of an Ionization Readout Tile for nEXO
nEXO Collaboration, M. Jewell, A. Schubert +142
A new design for the anode of a time projection chamber, consisting of a charge-detecting "tile", is investigated for use in large scale liquid xenon detectors. The tile is produce…
Trace radioactive impurities in final construction materials for EXO-200
D. S. Leonard, D. Auty, T. Didberidze +98
We report results from a systematic measurement campaign conducted to identify low radioactivity materials for the construction of the EXO-200 double beta decay experiment. Partial…
Measurement of the Drift Velocity and Transverse Diffusion of Electrons in Liquid Xenon with the EXO-200 Detector
200 Collaboration, J. B. Albert, P. S. Barbeau +84
The EXO-200 Collaboration is searching for neutrinoless double beta decay using a liquid xenon (LXe) time projection chamber. This measurement relies on modeling the transport of c…
An Optimal Energy Estimator to Reduce Correlated Noise for the EXO-200 Light Readout
200 Collaboration, C. G. Davis, C. Hall +84
The energy resolution of the EXO-200 detector is limited by electronics noise in the measurement of the scintillation response. Here we present a new technique to extract optimal s…
Investigation of radioactivity-induced backgrounds in EXO-200
J. B. Albert, D. J. Auty, P. S. Barbeau +83
The search for neutrinoless double-beta decay (0νββ) requires extremely low background and a good understanding of their sources and their influence on the rate in the region of pa…
Characterization of Silicon Photomultipliers for nEXO
I. Ostrovskiy, F. Retiere, D. Auty +9
Silicon Photomultipliers (SiPMs) are attractive candidates for light detectors for next generation liquid xenon double-beta decay experiments, like nEXO. In this paper we discuss t…
An apparatus to manipulate and identify individual Ba ions from bulk liquid Xe
K. Twelker, S. Kravitz, M. Montero Díez +77
We describe a system to transport and identify barium ions produced in liquid xenon, as part of R&D towards the second phase of a double beta decay experiment, nEXO. The goal is to…
