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…
Backscattering Study of Electrons from 0.1 to 3.4 MeV
M. Kanafani, X. Fléchard, O. Naviliat-Cuncic +10
Benchmarking simulation codes for electron transport and scattering in matter is a crucial step for estimating uncertainties in many applications. However, experimental data for el…
Magneto-: Heavy neutral lepton search using Pu $β^-$ decays
C. Lee, X. Zhang, A. Kavner +12
The MAGNETO- experiment searches for keV-scale heavy neutral leptons (HNLs) through precise measurements of the $β^-$-decay spectrum of Pu. We present spectra comprisi…
High-Precision Excited-State Nuclear Recoil Spectroscopy with Superconducting Sensors
C. Bray, S. Fretwell, L. A. Zepeda-Ruiz +30
Superconducting sensors doped with rare isotopes have recently demonstrated powerful sensing performance for sub-keV radiation from nuclear decay. Here, we report the first high-re…
Search for dark matter annual modulation with DarkSide-50
50 Collaboration, P. Agnes, I. F. M. Albuquerque +142
Dark matter induced event rate in an Earth-based detector is predicted to show an annual modulation as a result of the Earth's orbital motion around the Sun. We searched for this m…
