School Cosmic Ray Outreach Detector (SCROD)
L. A. Anchordoqui, J. Cook, M. Gabour +8
We report on our studies of applying novel detector technologies developed for LHC-era experiments to cosmic ray detection. In particular, we are investigating usage of scintillati…
Photoluminescence from surface GaN/AlGaN quantum wells: Effect of the surface states
Y. D. Glinka, T. V. Shahbazyan, H. O. Everitt +6
We report on photoluminescence (PL) measurements at 85 K for GaN/AlGaN surface quantum wells (SQW's) with a width in the range of 1.51-2.9 nm. The PL spectra show a redshift with d…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
The spectrum of (136199) Eris between 350 and 2350 nm: Results with X-Shooter
A. Alvarez-Candal, N. Pinilla-Alonso, J. Licandro +7
X-Shooter is the first second-generation instrument for the ESO-VLT. It as a spectrograph covering the 300 - 2480 nm spectral range at once with a high resolving power. These prope…
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…
Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics
The ATLAS Collaboration, G. Aad, E. Abat +2604
A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together w…
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…
Projectile Fragmentation of Kr at 64 MeV/nucleon
M. Mocko, M. B. Tsang, Z. Y. Sun +18
We measured fragmentation cross sections produced using the primary beam of Kr at 64 MeV/nucleon on Be and Ta targets. The cross sections were obtained by integr…
Aliasing from Galactic Plane Setting in Widefield Radio Interferometry
N. Barry, J. L. B. Line, C. R. Lynch +2
Measurements with widefield radio interferometers often include the near-infinite gradient between the sky and the horizon. This causes aliasing inherent to the measurement itself,…
Competition between normal and intruder states inside the "Island of Inversion"
Vandana Tripathi, S. L. Tabor, P. F. Mantica +13
The beta decay of the exotic 30Ne (N=20) is reported. For the first time, the low-energy level structure of the N=19, 30Na (Tz = 4), is obtained from beta-delayed gamma spectroscop…
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…
Unveiling the ice and gas nature of active centaur (2060) Chiron using the James Webb Space Telescope
N. Pinilla-Alonso, J. Licandro, R. Brunetto +15
(2060) Chiron is a large centaur that has been reported active on multiple occasions including during aphelion passage. Studies of Chirons coma during active periods have resulted…
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…
