Design and Characterization of a Phonon-Mediated Cryogenic Particle Detector with an eV-Scale Threshold and 100 keV-Scale Dynamic Range
R. Ren, C. Bathurst, Y. Y. Chang +27
We present the design and characterization of a cryogenic phonon-sensitive 1-gram Si detector exploiting the Neganov-Trofimov-Luke effect to detect single-charge excitations. This…
Constraints on Lightly Ionizing Particles from CDMSlite
SuperCDMS Collaboration, I. Alkhatib, D. W. P. Amaral +115
The Cryogenic Dark Matter Search low ionization threshold experiment (CDMSlite) achieved efficient detection of very small recoil energies in its germanium target, resulting in sen…
Photoelectric absorption cross section of silicon near the band gap from room temperature to sub-Kelvin temperature
C. Stanford, M. J. Wilson, B. Cabrera +6
The use of cryogenic silicon as a detector medium for dark matter searches is gaining popularity. Many of these searches are highly dependent on the value of the photoelectric abso…
Limits on the Existence of sub-MeV Sterile Neutrinos from the Decay of Be in Superconducting Quantum Sensors
S. Friedrich, G. B. Kim, C. Bray +14
Sterile neutrinos are natural extensions to the standard model of particle physics and provide a possible portal to the dark sector. We report a new search for the existence of sub…

I. Alkhatib, D. W. P. Amaral, T. Aralis +121
We present limits on spin-independent dark matter-nucleon interactions using a Si athermal phonon detector with a baseline energy resolution of $σ_E=3.86 \pm 0.…
Constraints on low-mass, relic dark matter candidates from a surface-operated SuperCDMS single-charge sensitive detector
SuperCDMS Collaboration, D. W. Amaral, T. Aralis +116
This article presents an analysis and the resulting limits on light dark matter inelastically scattering off of electrons, and on dark photon and axion-like particle absorption, us…
Direct measurement of the Be capture ratio in Ta-based superconducting tunnel junctions
S. Fretwell, K. G. Leach, C. Bray +8
We report a high-statistics measurement of the orbital electron capture (EC) ratio in Be embedded in cryogenic Ta. The thin Ta film formed part of a high-resolution super…
