Charge Trap Analysis in a SENSEI Skipper-CCD: Understanding Low-Energy Backgrounds in Rare-Event Searches
Agustin Brusco, Bruno Sivilotti, Ana M. Botti +14
Skipper Charge-Coupled Devices (Skipper-CCDs) are ultra-low-threshold detectors capable of detecting energy deposits in silicon at the eV scale. Increasingly used in rare-event sea…
Low-Energy Backgrounds in Solid-State Phonon and Charge Detectors
Daniel Baxter, Rouven Essig, Yonit Hochberg +5
Solid-state phonon and charge detectors probe the scattering of weakly interacting particles, such as dark matter and neutrinos, through their low recoil thresholds. Recent advance…
Probing Millicharged Particles at an Electron Beam Dump with Ultralow-Threshold Sensors
Rouven Essig, Peiran Li, Zhen Liu +3
We propose to search for millicharged particles produced in high-intensity electron beam dumps using small ultralow-threshold sensors. As a concrete example, we consider a Skipper-…
SENSEI at SNOLAB: Single-Electron Event Rate and Implications for Dark Matter
Itay M. Bloch, Ana M. Botti, Mariano Cababie +27
We present results from data acquired by the SENSEI experiment at SNOLAB after a major upgrade in May 2023, which includes deploying 16 new sensors and replacing the copper trays t…
