Characterization of Aluminum Microwave SQUID Multiplexers for CENS Detection
James Amidei, Antoine Armatol, Corinne Augier +92
We present the design, fabrication, and characterization of an aluminum-based six-channel microwave SQUID multiplexer (MUX) prototype for transition-edge sensor (TES) readout i…
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…
First observation of single beta decay of Zr
A. S. Barabash, S. Evseev, D. Filosofov +14
The single beta decay of Zr has been detected for the first time using a 211 cm low-background HPGe detector and an external source consisting of two samples of enriched…
First investigation of Zr samples enriched by the gas-centrifuge method for the use in rare-decay studies
D. Arefev, A. S. Barabash, M. De Jesus +21
For the first time, the isotope Zr has been produced by the gas-centrifuge method (enrichment is 88.28% and full mass of Zr is 179.816 g). The level of radionuclide i…
Application of a high-precision distributed uranium source for determining the effective mass and volume of a HPGe detector
A. S. Barabash, S. Evseev, D. Filosofov +10
A distributed uranium source with the accurately certified activity of 238U has been used to verify the effective mass of the HPGe detector intended for the νGeN neutrino experime…
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…
