Radiopurity material assays and radiation exposure projections for superconducting qubit measurements at SNOLAB
Y. Ahmed, B. Binoy, R. Bunker +21
Interactions of cosmic rays and other forms of ionizing radiation pose a significant challenge to the reliable operation of state-of-the-art quantum devices and error correction in…
Calibration and Performance of Germanium High Voltage Detectors for SuperCDMS SNOLAB
M. F. Albakry, I. Alkhatib, D. Alonso-González +140
As SuperCDMS SNOLAB is getting ready to search for low mass dark matter particles, using cryogenic Ge and Si detectors, a set of six of the new SuperCDMS High Voltage (HV) detector…
Performance of a SuperCDMS HVeV Detector with Sub-eV Energy Resolution and Single Charge-sensitivity
Kyle Kennard, Aditi Pradeep, Mason Buchanan +41
We present a detailed characterization of a new generation of athermal-phonon single-charge sensitive Si HVeV detectors, the best of which achieved 589~meV~~5~meV baseline res…
Exploring Low Energy Excess in MINER with sapphire detectors using Convolutional Variational Autoencoder (CVAE)
D. Mondal, W. Baker, M. Chaudhuri +19
As cryogenic detectors push toward ever-lower energy thresholds, their sensitivity is increasingly constrained by a persistent low-energy background known as the low-energy excess…
Characterization of Aluminum Microwave SQUID Multiplexers for CENS Detection
James Amidei, Antoine Armatol, Corinne Augier +92
We present the design, fabrication, and characterization of an aluminum-based six-channel microwave SQUID multiplexer (MUX) prototype for transition-edge sensor (TES) readout i…
Search for low-mass electron-recoil dark matter using a single-charge sensitive SuperCDMS-HVeV Detector
SuperCDMS Collaboration, M. F. Albakry, I. Alkhatib +146
We present constraints on low-mass dark matter electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken undergr…
