A First Demonstration of the SQUAT Detector Architecture: Direct Measurement of Resonator-Free Charge-Sensitive Transmons
H. Magoon, T. Aralis, T. Dyson +18
The Superconducting Quasiparticle-Amplifying Transmon (SQUAT) is a new sensor architecture for THz (meV) detection based on a weakly charge-sensitive transmon directly coupled to a…
SPLENDOR: a novel detector platform to search for light dark matter with narrow-gap semiconductors
P. Abbamonte, A. Albert, D. S. M. Alves +31
We present the design and current status of SPLENDOR, a novel detector platform that combines narrow-gap semiconductor targets with low-noise charge readout to achieve sensitivity…
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 Limits on Light Dark Matter Interactions in a Low Threshold Two Channel Athermal Phonon Detector from the TESSERACT Collaboration
C. L. Chang, Y. -Y. Chang, L. Chaplinsky +45
We present results of a search for spin-independent dark matter-nucleon interactions in a 1 cm by 1 mm thick (0.233 gram) high-resolution silicon athermal phonon detector opera…
The Superconducting Quasiparticle-Amplifying Transmon: A Qubit-Based Sensor for meV Scale Phonons and Single THz Photons
Caleb W. Fink, Chiara P. Salemi, Betty A. Young +2
With great interest from the quantum computing community, an immense amount of R&D effort has been invested into improving superconducting qubits. The technologies developed for th…
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…
