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…
Search for Neutrinoless Double-Beta Decay in Xe with EXO-200
M. Auger, D. J. Auty, P. S. Barbeau +75
We report on a search for neutrinoless double-beta decay of Xe with EXO-200. No signal is observed for an exposure of 32.5 kg-yr, with a background of ~1.5 x 10^{-3} /(kg y…
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…
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…
Systematic study of trace radioactive impurities in candidate construction materials for EXO-200
D. S. Leonard, P. Grinberg, P. Weber +54
The Enriched Xenon Observatory (EXO) will search for double beta decays of 136Xe. We report the results of a systematic study of trace concentrations of radioactive impurities in a…
