Dark matter searches and energy accumulation and release in materials
Sergey Pereverzev
Efforts to identify dark matter by detecting nuclear recoils produced by dark matter particles reveal low-energy backgrounds of unknown origin in different types of detectors. In m…
What surfaces in the operation of noble liquids dark matter detectors
Sergey Pereverzev
Electron and ion accumulation atop liquid can lead to formation of macroscopic charged hillocks and electrospraying, small signal suppression by charged crust. Design changes for l…
Excess backgrounds in Dark Matter detectors and physics of glasses
Sergey Pereverzev
In solid-state dark matter detectors, energy accumulation due to ionizing radiation should produce delayed low-energy background similar to the background produced by energy deposi…
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…
Thermodynamic Stability of Xenon-Doped Liquid Argon Detectors
Ethan P. Bernard, Eli Mizrachi, James Kingston +12
Liquid argon detectors are employed in a wide variety of nuclear and particle physics experiments. The addition of small quantities of xenon to argon modifies its scintillation, io…
Production and suppression of delayed light in NaI
F. Sutanto, J. Xu, S. Pereverzev +1
We investigate a hypothesis that energy accumulation and the subsequent release in NaI(Tl) may lead to pulse-like events in the few-keV energy regime, a phenomenon suggested by the…
Snowmass2021 Cosmic Frontier White Paper: Calibrations and backgrounds for dark matter direct detection
Daniel Baxter, Raymond Bunker, Sally Shaw +48
Future dark matter direct detection experiments will reach unprecedented levels of sensitivity. Achieving this sensitivity will require more precise models of signal and background…
Superconducting Nanowire Single-Photon Detectors and effect of accumulation and unsteady releases of excess energy in materials
Sergey Pereverzev, Gianpaolo Carosi, Viacheslav Li
Universal fault-tolerant quantum computers, which promise to revolutionize computing, are currently limited by excessive noise in their constituent superconducting qubits. Determin…
Detecting Low-Energy Interactions and the Effects of Energy Accumulation in Materials
Sergey Pereverzev
We hypothesize that avalanche-like releases of energy accumulated in materials due to radioactivity and other sources can produce parasitic background in dark matter particles sear…
LBECA: A Low Background Electron Counting Apparatus for Sub-GeV Dark Matter Detection
A. Bernstein, M. Clark, R. Essig +12
Two-phase noble liquid detectors, with large target masses and effective background reduction, are currently leading the dark matter direct detection for WIMP masses above a few Ge…
Proceedings of The Magnificent CENS Workshop 2018
D. Aristizabal Sierra, A. B. Balantekin, D. Caratelli +42
The Magnificent CENS Workshop (2018) was held November 2 & 3 of 2018 on the University of Chicago campus and brought together theorists, phenomenologists, and experimentalists w…
Measurement of the ionization yield from nuclear recoils in liquid xenon between 0.3 -- 6 keV with single-ionization-electron sensitivity
