Energy Calibration and Performance of HPGe Detectors in the LEGEND-200 Experiment
The LEGEND Collaboration, H. Acharya, M. Agostini +259
This paper describes the energy scale procedures and germanium detectors performance in the LEGEND-200 experiment, a critical component for the first unblinding in the search for n…
Procurement and Purification of Liquid Argon for the LEGEND-200 Experiment
Malgorzata HaraÅczyk, Patrick Krause, Tomasz Mróz +8
LEGEND-200 requires high-purity liquid argon for effective background discrimination. In this paper, we present the design, construction, and performance of a dedicated liquid argo…
Determination of the Muon Lifetime in Se with the MONUMENT experiment
G. R. Araujo, D. Bajpai, L. Baudis +26
Ordinary muon capture provides a benchmark for the nuclear physics models of neutrinoless double beta decay under comparable momentum transfer conditions. The total capture strengt…
First operation of poly(ethylene naphthalate) enclosures for high-purity germanium detectors in liquid argon for K/Ar mitigation
Christoph Vogl, Tommaso Comellato, Konstantin Gusev +10
Commercial argon contains cosmogenic Ar whose progeny K is a critical background component for the Large Enriched Germanium Experiment for Neutrinoless Decay (…
Ar Production and Injection to a Liquid Argon Environment for Background Mitigation Studies
Mario Schwarz, Christoph Vogl, Niko N. P. N. Lay +6
Atmosphere-sourced argon contains traces of Ar, whose $β^-$-decaying progeny K represents a significant intrinsic background for rare-event experiments using liquid…
First Results on the Search for Lepton Number Violating Neutrinoless Double Beta Decay with the LEGEND-200 Experiment
H. Acharya, N. Ackermann, M. Agostini +256
The LEGEND collaboration is searching for neutrinoless double beta () decay by operating high-purity germanium detectors enriched in Ge in a low-background liquid a…
