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…
