Aluminum-Based Superconducting Tunnel Junction Sensors for Nuclear Recoil Spectroscopy
Spencer L. Fretwell, Connor Bray, Inwook Kim +31
The BeEST experiment is searching for sub-MeV sterile neutrinos by measuring nuclear recoil energies from the decay of Be implanted into superconducting tunnel junction (STJ) s…
Integration of Silica in G4CMP for Phonon Simulations: Framework and Tools for Material Integration
Caitlyn Stone-Whitehead, Israel Hernandez, Connor Bray +10
Superconducting detectors with sub-eV energy resolution have demonstrated success setting limits on Beyond the Standard Model (BSM) physics due to their unique sensitivity to low-e…
Next Generation Ta-STJ Sensor Arrays for BSM Physics Searches
Joseph P. T. Templet, Spencer Fretwell, Andrew Marino +9
The Beryllium Electron capture in Superconducting Tunnel junctions (BeEST) experiment uses superconducting tunnel junction (STJ) sensors to search for physics beyond the standard m…
Shake-up and shake-off spectra in the electron capture decay of atomic Be
Mauro Guerra, Inwook Kim, Stephan Friedrich +33
The most stringent laboratory-based experimental limits on the existence of sub-MeV sterile neutrinos are currently set by decay spectroscopy of radioactive Be embedded into su…
Simulation of Muon-induced Backgrounds for the Colorado Underground Research Institute (CURIE)
Dakota K. Keblbeck, Eric Mayotte, Uwe Greife +5
We present a comprehensive Monte Carlo simulation of muon-induced backgrounds for the Colorado Underground Research Institute (CURIE), a shallow-underground facility with $\approx…
