Single-electron detection in a high-purity Ge device
Antoine Armatol, Corinne Augier, Laurent Bergé +69
High-purity germanium (HPGe) detectors are among the most powerful instruments for gamma ray spectroscopy, combining exceptional energy resolution with large active volumes. Althou…
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 in…
Design Studies Of A Pulsed Quasimonoenergetic 2-keV Neutron Source For Calibration Of Low Threshold Dark Matter Detectors
L. Chaplinsky, S. Fiorucci, C. W. Fink +25
We describe design studies for a pulsed quasi-monoenergetic 2-keV neutron source for calibration of sub-keV nuclear recoils. Such a calibration is required for detectors sensitive…
Low Energy Backgrounds and Excess Noise in a Two-Channel Low-Threshold Calorimeter
Robin Anthony-Petersen, Clarence L. Chang, Yen-Yung Chang +29
We describe observations of low energy excess (LEE) events, background events observed in all light dark matter direct detection calorimeters, and noise in a Transition Edge Sensor…
First Demonstration of the HeRALD Superfluid Helium Detector Concept
R. Anthony-Petersen, A. Biekert, C. L. Chang +33
The SPICE/HeRALD collaboration is performing R&D to enable studies of sub-GeV dark matter models using a variety of target materials. Here we report our recent progress on instrume…
Results from a Prototype TES Detector for the Ricochet Experiment
Ricochet Collaboration, C. Augier, G. Baulieu +88
Coherent elastic neutrino-nucleus scattering (CENS) offers valuable sensitivity to physics beyond the Standard Model. The Ricochet experiment will use cryogenic solid-state dete…
A portable and high intensity 24 keV neutron source based on Sb-Be photoneutrons and an iron filter
A. Biekert, C. Chang, L. Chaplinsky +27
A portable monoenergetic 24 keV neutron source based on the Sb-Be photoneutron reaction and an iron filter has been constructed and characterized. The coincidence of th…
A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning
Robin Anthony-Petersen, Andreas Biekert, Raymond Bunker +43
The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condit…
A backing detector for order-keV neutrons
A. Biekert, L. Chaplinsky, C. W. Fink +23
We have designed and tested a large-area (0.15~m) neutron detector based on neutron capture on \ce{^{6}Li}. The neutron detector design has been optimized for the purpose of ta…
Ricochet Progress and Status
Ricochet Collaboration, G. Beaulieu, V. Belov +77
We present an overview of recent progress towards the Ricochet coherent elastic neutrino nucleus scattering CENS experiment. The ILL research reactor in Grenoble, France has bee…
SENSEI: Characterization of Single-Electron Events Using a Skipper-CCD
Liron Barak, Itay M. Bloch, Ana Botti +22
We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the orig…
