Robustness of superconductivity to structural disorder in Sr(NH)(NH)FeSe
F. R. Foronda, S. Ghannadzadeh, S. J. Sedlmaier +7
The superconducting properties of a recently discovered high superconductor, Sr/ammonia-intercalated FeSe, have been measured using pulsed magnetic fields down to $4.\,…
Measurements of the ion fraction and mobility of alpha and beta decay products in liquid xenon using EXO-200
J. B. Albert, D. J. Auty, P. S. Barbeau +82
Alpha decays in the EXO-200 detector are used to measure the fraction of charged and daughters created from alpha and beta decays, respectiv…
Search for Majorana neutrinos with the first two years of EXO-200 data
200 Collaboration, J. B. Albert, D. J. Auty +91
Many extensions of the Standard Model of particle physics suggest that neutrinos should be Majorana-type fermions, but this assumption is difficult to confirm. Observation of neutr…
The upper critical field of NaFeCoAs superconductors
S. Ghannadzadeh, J. D. Wright, F. R. Foronda +3
The upper critical field of NaFeCoAs was measured from to , with the magnetic field applied parallel () and normal ($H_{\rm c2}^\per…
Magnetic fluctuations and spin freezing in nonsuperconducting LiFeAs derivatives
J. D. Wright, M. J. Pitcher, W. Trevelyan-Thomas +5
We present detailed magnetometry and muon-spin rotation data on polycrystalline samples of overdoped, non-superconducting LiFeNiAs () and LiFe$_{…
An improved measurement of the 2νββ half-life of Xe-136 with EXO-200
J. B. Albert, M. Auger, D. J. Auty +94
We report on an improved measurement of the 2νββ half-life of Xe-136 performed by EXO-200. The use of a large and homogeneous time projection chamber allows for the precise estimat…
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…
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…
The gradual destruction of magnetism in the superconducting family NaFe(1-x)CoxAs
J. D. Wright, T. Lancaster, I. Franke +10
The interplay and coexistence of superconducting, magnetic and structural order parameters in NaFe{1-x}Co{x}As has been studied using SQUID magnetometry, muon-spin rotation and syn…
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…
Metastable helium molecules as tracers in superfluid liquid He
W. Guo, J. D. Wright, S. B. Cahn +2
Metastable helium molecules generated in a discharge near a sharp tungsten tip operated in either pulsed mode or continuous field-emission mode in superfluid liquid He are im…
