CAGE: An Internal Source Scanning Cryostat for HPGe Characterization
G. Othman, C. Wiseman, T. H. Burritt +8
The success of current and future-generation neutrinoless double beta decay experiments relies on the ability to eliminate or reduce extraneous backgrounds. In addition to construc…
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…
Rare multi-nucleon decays with the full data sets of the Majorana Demonstrator
I. J. Arnquist, F. T. Avignone, A. S. Barabash +39
The Majorana Demonstrator was an ultra-low-background experiment designed for neutrinoless double-beta decay () investigation in Ge. Located at the Sanford Undergro…
Final Results of the MAJORANA DEMONSTRATOR's Search for Double-Beta Decay of Ge to Excited States of Se
I. J. Arnquist, F. T. Avignone, A. S. Barabash +45
Ge can decay into three possible excited states of Se, with the emission of two or, if the neutrino is Majorana, zero neutrinos. None of these six transitions…
Search for charge nonconservation and Pauli exclusion principle violation with the Majorana Demonstrator
MAJORANA Collaboration, I. J. Arnquist, F. T. Avignone +55
Charge conservation and the Pauli exclusion principle result from fundamental symmetries in the standard model of particle physics, and are typically taken as axiomatic. High-preci…
The MAJORANA DEMONSTRATOR experiment's construction, commissioning, and performance
N. Abgrall, E. Aguayo, I. J. Arnquist +108
Background: The MAJORANA DEMONSTRATOR , a modular array of isotopically enriched high-purity germanium (HPGe) detectors, was constructed to demonstrate backgrounds low enough to ju…
