First Nuclear Ultra-Heavy Dark Matter Search in Argon Time Projection Chambers with the DarkSide-50 Experiment
P. Agnes, I. F. Albuquerque, T. Alexander +125
We report the first search for nuclear ultra-heavy dark matter (UHDM) in a dual-phase liquid argon time projection chamber using the DarkSide-50 experiment. Unlike conventional wea…
Novel High-Radiopurity Doped Amorphous Silicon Resistors for Low-Background Detectors
A. Anker, P. C. Rowson, K. Skarpaas +9
We present the results of a study of lightly doped amorphous silicon used as a resistive medium for high-radiopurity resistors in nuclear and particle physics research instrumentat…
The nEXO Radioassay Program
R. MacLellan, P. Acharya, B. Aharmim +148
Material radioactivity compilations, such as the one presented here, are important enablers of science. They are useful for the selection of radiopure materials used in the design…
Fermionic sub-GeV Dark Matter from evaporating Primordial Black Holes at DarkSide-50
50 Collaboration, P. Agnes, I. F. Albuquerque +125
We present a search for boosted dark matter from Primordial Black Holes (PBH) evaporation using the DarkSide-50 ionization-signal-only dataset corresponding to the experiment's ($1…
Characterization of CRYO ASIC for charge readout in the nEXO experiment
Z. Li, M. Yu, E. Angelico +141
nEXO is a proposed next-generation experiment searching for the neutrinoless double beta decay of Xe using a tonne-scale liquid xenon (LXe) time projection chamber (TPC). T…
Removal of spallation-induced tritium from silicon through diffusion
R. Saldanha, D. Reading, P. E. Warwick +5
Tritium, predominantly produced through spallation reactions caused by cosmic ray interactions, is a significant radioactive background for silicon-based rare event detection exper…
