Reflectance and fluorescence characteristics of PTFE coated with TPB at visible, UV, and VUV as a function of thickness
J. Haefner, A. Fahs, J. Ho +100
Polytetrafluoroethylene (PTFE) is an excellent diffuse reflector widely used in light collection systems for particle physics experiments. In noble element systems, it is often coa…
Snowmass Instrumentation Frontier IF08 Topical Group Report: Noble Element Detectors
Carl Eric Dahl, Roxanne Guenette, Jennifer L. Raaf +39
Particle detectors making use of noble elements in gaseous, liquid, or solid phases are prevalent in neutrino and dark matter experiments and are also used to a lesser extent in co…
The Dynamics of Ions on Phased Radio-frequency Carpets in High Pressure Gases and Application for Barium Tagging in Xenon Gas Time Projection Chambers
NEXT Collaboration, B. J. P. Jones, A. Raymond +107
Radio-frequency (RF) carpets with ultra-fine pitches are examined for ion transport in gases at atmospheric pressures and above. We develop new analytic and computational methods f…
Sensitivity of a tonne-scale NEXT detector for neutrinoless double beta decay searches
NEXT Collaboration, C. Adams, V. Álvarez +96
The Neutrino Experiment with a Xenon TPC (NEXT) searches for the neutrinoless double-beta decay of Xe-136 using high-pressure xenon gas TPCs with electroluminescent amplification.…
Surface background suppression in liquid argon dark matter detectors using a newly discovered time component of tetraphenyl-butadiene scintillation
Chris Stanford, Shawn Westerdale, Jingke Xu +1
Decays of radioisotopes on inner detector surfaces can pose a major background concern for the direct detection of dark matter. While these backgrounds are conventionally mitigated…
Electroluminescence pulse shape and electron diffusion in liquid argon measured in a dual-phase TPC
P. Agnes, I. F. M. Albuquerque, T. Alexander +163
We report the measurement of the longitudinal diffusion constant in liquid argon with the DarkSide-50 dual-phase time projection chamber. The measurement is performed at drift elec…
The Electronics, Trigger and Data Acquisition System for the Liquid Argon Time Projection Chamber of the DarkSide-50 Search for Dark Matter
DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +177
The DarkSide-50 experiment at the Laboratori Nazionali del Gran Sasso is a search for dark matter using a dual phase time projection chamber with 50 kg of low radioactivity argon a…
Simulation of argon response and light detection in the DarkSide-50 dual phase TPC
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +147
A Geant4-based Monte Carlo package named G4DS has been developed to simulate the response of DarkSide-50, an experiment operating since 2013 at LNGS, designed to detect WIMP intera…
Cryogenic Characterization of FBK RGB-HD SiPMs
C. E. Aalseth, F. Acerbi, P. Agnes +268
We report on the cryogenic characterization of Red Green Blue - High Density (RGB-HD) SiPMs developed at Fondazione Bruno Kessler (FBK) as part of the DarkSide program of dark matt…
Effect of Low Electric Fields on Alpha Scintillation Light Yield in Liquid Argon
P. Agnes, I. F. M. Albuquerque, T. Alexander +158
Measurements were made of scintillation light yield of alpha particles from the Rn decay chain within the DarkSide-50 liquid argon time projection chamber. The light yield…
CALIS - a CALibration Insertion System for the DarkSide-50 dark matter search experiment
P. Agnes, I. F. M. Albuquerque, T. Alexander +162
This paper describes the design, fabrication, commissioning and use of a CALibration source Insertion System (CALIS) in the DarkSide-50 direct dark matter search experiment. CALIS…
First measurement of surface nuclear recoil background for argon dark matter searches
Jingke Xu, Chris Stanford, Shawn Westerdale +3
One major background in direct searches for weakly interacting massive particles (WIMPs) comes from the deposition of radon progeny on detector surfaces. The most dangerous surface…

DarkSide-50 is a detector for dark matter candidates in the form of weakly interacting massive particles (WIMPs). It utilizes a liquid argon time projection chamber (LAr TPC) for t…
The veto system of the DarkSide-50 experiment
The DarkSide Collaboration, P. Agnes, L. Agostino +158
Nuclear recoil events produced by neutron scatters form one of the most important classes of background in WIMP direct detection experiments, as they may produce nuclear recoils th…
