EXO-200 Public Data Release for AI/ML Applications
S. Al Kharusi, G. Anton, I. Badhrees +103
We present a public release of a subset of calibration data from the EXO-200 experiment, a liquid xenon time projection chamber designed to search for neutrinoless double-beta deca…
Ion manipulation from liquid Xe to vacuum: Ba-tagging for a nEXO upgrade and future experiments
Dwaipayan Ray, Robert Collister, Hussain Rasiwala +27
Neutrinoless double beta decay {()} provides a way to probe physics beyond the Standard Model of particle physics. The upcoming nEXO experiment will search for decay i…
The EXO-200 detector, part II: Auxiliary Systems
N. Ackerman, J. Albert, M. Auger +157
The EXO-200 experiment searched for neutrinoless double-beta decay of Xe with a single-phase liquid xenon detector. It used an active mass of 110 kg of 80.6%-enriched liqui…
Measurement of the scintillation and ionization response of liquid xenon at MeV energies in the EXO-200 experiment
200 Collaboration, G. Anton, I. Badhrees +99
Liquid xenon (LXe) is employed in a number of current and future detectors for rare event searches. We use the EXO-200 experimental data to measure the absolute scintillation and i…
Study of Silicon Photomultiplier Performance in External Electric Fields
X. L. Sun, T. Tolba, G. F. Cao +149
We report on the performance of silicon photomultiplier (SiPM) light sensors operating in electric field strength up to 30 kV/cm and at a temperature of 149K, relative to their per…
VUV-sensitive Silicon Photomultipliers for Xenon Scintillation Light Detection in nEXO
A. Jamil, T. Ziegler, P. Hufschmidt +140
Future tonne-scale liquefied noble gas detectors depend on efficient light detection in the VUV range. In the past years Silicon Photomultipliers (SiPMs) have emerged as a valid al…
nEXO Pre-Conceptual Design Report
nEXO Collaboration, S. Al Kharusi, A. Alamre +171
The projected performance and detector configuration of nEXO are described in this pre-Conceptual Design Report (pCDR). nEXO is a tonne-scale neutrinoless double beta () deca…
Deep Neural Networks for Energy and Position Reconstruction in EXO-200
S. Delaquis, M. J. Jewell, I. Ostrovskiy +91
We apply deep neural networks (DNN) to data from the EXO-200 experiment. In the studied cases, the DNN is able to reconstruct the relevant parameters - total energy and position -…
Characterization of an Ionization Readout Tile for nEXO
nEXO Collaboration, M. Jewell, A. Schubert +142
A new design for the anode of a time projection chamber, consisting of a charge-detecting "tile", is investigated for use in large scale liquid xenon detectors. The tile is produce…
Trace radioactive impurities in final construction materials for EXO-200
D. S. Leonard, D. Auty, T. Didberidze +98
We report results from a systematic measurement campaign conducted to identify low radioactivity materials for the construction of the EXO-200 double beta decay experiment. Partial…
