An RF-only ion-funnel for extraction from high-pressure gases
Thomas Brunner, Daniel Fudenberg, Victor Varentsov +74
An RF ion-funnel technique has been developed to extract ions from a high-pressure (10 bar) noble-gas environment into vacuum ( mbar). Detailed simulations have been perfo…
Solid state breakdown counter for magnetic monopole and other highly ionizing particles searches
Igor Ostrovskiy, James Pinfold
Solid state breakdown counters combine threshold properties of nuclear track detectors with the convenience of electronic event registration in real time. Here we discuss the princ…
Spectroscopy of Ba and Ba deposits in solid xenon for barium tagging in nEXO
B. Mong, S. Cook, T. Walton +73
Progress on a method of barium tagging for the nEXO double beta decay experiment is reported. Absorption and emission spectra for deposits of barium atoms and ions in solid xenon m…
Search for Majoron-emitting modes of double-beta decay of Xe with EXO-200
200 Collaboration, J. B. Albert, D. J. Auty +89
EXO-200 is a single phase liquid xenon detector designed to search for neutrinoless double-beta decay of Xe. Here we report on a search for various Majoron-emitting modes b…
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 Majorana neutrinos with the first two years of EXO-200 data
200 Collaboration, J. B. Albert, D. J. Auty +91
Many extensions of the Standard Model of particle physics suggest that neutrinos should be Majorana-type fermions, but this assumption is difficult to confirm. Observation of neutr…
