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…
The EXO-200 detector, part I: Detector design and construction
M. Auger, D. J. Auty, P. S. Barbeau +78
EXO-200 is an experiment designed to search for double beta decay of Xe with a single-phase, liquid xenon detector. It uses an active mass of 110 kg of xenon enriched to 80…
Xenon purity analysis for EXO-200 via mass spectrometry
A. Dobi, C. Hall, S. Slutsky +73
We describe purity measurements of the natural and enriched xenon stockpiles used by the EXO-200 double beta decay experiment based on a mass spectrometry technique. The sensitivit…
Observation of Two-Neutrino Double-Beta Decay in Xe-136 with EXO-200
N. Ackerman, B. Aharmim, M. Auger +100
We report the observation of two-neutrino double-beta decay in Xe-136 with T_1/2 = 2.11 +- 0.04 (stat.) +- 0.21 (sys.) x 10^21 yr. This second order process, predicted by the Stand…
A xenon gas purity monitor for EXO
EXO Collaboration, A. Dobi, C. Hall +57
We discuss the design, operation, and calibration of two versions of a xenon gas purity monitor (GPM) developed for the EXO double beta decay program. The devices are sensitive to…
A magnetically-driven piston pump for ultra-clean applications
F. LePort, R. Neilson, P. S. Barbeau +77
A magnetically driven piston pump for xenon gas recirculation is presented. The pump is designed to satisfy extreme purity and containment requirements, as is appropriate for the r…
A simple radionuclide-driven single-ion source
M. Montero Díez, K. Twelker, W. Fairbank +54
We describe a source capable of producing single barium ions through nuclear recoils in radioactive decay. The source is fabricated by electroplating 148Gd onto a silicon α-particl…
The case for a directional dark matter detector and the status of current experimental efforts
S. Ahlen, N. Afshordi, J. B. R. Battat +109
We present the case for a dark matter detector with directional sensitivity. This document was developed at the 2009 CYGNUS workshop on directional dark matter detection, and conta…
Low Energy Electron and Nuclear Recoil Thresholds in the DRIFT-II Negative Ion TPC for Dark Matter Searches
S. Burgos, E. Daw, J. Forbes +18
Understanding the ability to measure and discriminate particle events at the lowest possible energy is an essential requirement in developing new experiments to search for weakly i…
First measurement of the Head-Tail directional nuclear recoil signature at energies relevant to WIMP dark matter searches
S. Burgos, E. Daw, J. Forbes +19
We present first evidence for the so-called Head-Tail asymmetry signature of neutron-induced nuclear recoil tracks at energies down to 1.5 keV/amu using the 1m^3 DRIFT-IIc dark mat…
Measurement of the Range Component Directional Signature in a DRIFT-II Detector using 252Cf Neutrons
S. Burgos, E. Daw, J. Forbes +19
The DRIFT collaboration utilizes low pressure gaseous detectors to search for WIMP dark matter with directional signatures. A 252Cf neutron source was placed on each of the princip…
