Demonstration of a cryogenic, switchable electron source for low-temperature detector calibration
D. A. Bennett, M. Borghesi, P. Campana +17
We present the realization of a prototype of a compact, switchable electron source operating at cryogenic temperatures, demonstrated at energies ranging from 100 eV to 300 eV, and…

Phenomenological Modeling of the Ho Calorimetric Electron Capture Spectrum from the HOLMES Experiment
F. Ahrens, B. K. Alpert, D. T. Becker +46
We present a comprehensive phenomenological analysis of the calorimetric electron capture (EC) decay spectrum of Ho as measured by the HOLMES experiment. Using high-statist…

Most stringent bound on electron neutrino mass obtained with a scalable low temperature microcalorimeter array
B. K. Alpert, M. Balata, D. T. Becker +36
The determination of the absolute neutrino mass scale remains a fundamental open question in particle physics, with profound implications for both the Standard Model and cosmology.…
