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…
Tantalum Damascene Coplanar Waveguide Resonators Fabricated Using 300 mm Scale Processes
Ekta Bhatia, Yingge Du, Krishna P Koirala +12
Surface oxides contribute to losses in superconducting transmon devices resulting in degraded performance. We explore the use of the damascene process to replace the sidewall nativ…
Internal Charge Amplification in Germanium at 77K and 4K: From Single-Free-Flight Bounds to a Physics-Informed Ionization Model
Dongming Mei, Kunming Dong, Narayan Budhathoki +2
Internal charge amplification (ICA) in cryogenic high-purity germanium (HPGe) can lower detection thresholds by providing gain inside the detector crystal, but reliable operation r…
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…
Signal processing and spectral modeling for the BeEST experiment
Inwook Kim, Connor Bray, Andrew Marino +35
The Beryllium Electron capture in Superconducting Tunnel junctions (BeEST) experiment searches for evidence of heavy neutrino mass eigenstates in the nuclear electron capture decay…
