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…
Design of a high voltage delivery system for noble liquid time projection chambers
R. Saldanha, L. Pagani, E. Angelico +129
Noble liquid time projection chambers (TPCs) are a leading technology in the detection of ionizing radiation, particularly in applications such as accelerator neutrino physics, dar…
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…
Search for Double Beta Decays of Xe with EXO-200 Phase II
S. Al Kharusi, G. Anton, I. Badhrees +104
EXO-200 was a leading double beta decay experiment consisting of a single-phase, enriched liquid xenon time projection chamber filled with an admixture of 80.672% Xe and 19…
Measuring dark currents in multiple cryogenic SiPMs with sub-pA sensitivity using an automated IV multiplexer
Lucas Darroch, Eamon Egan, Marc-Antoine Leclerc +2
We present the design of an automated current-voltage (IV) multiplexer (MUX) that enables accurate measurement of the dark current in cryogenic silicon photomultipliers (SiPMs), ac…
Ultra-pure Nickel for Structural Components of Low-Radioactivity Instruments
T. J. Roosendaal, C. T. Overman, G. S. Ortega +123
The next generation of rare-event search experiments in nuclear and particle physics demand structural materials combining exceptional mechanical strength with ultra-low levels of…
