CMOS Image Sensors for CEvNS Detection at Nuclear Reactors

Santiago Ezequiel Perez, Dario Rodrigues, Miguel Sofo-Haro

In this work we present Complementary Metal-Oxide-Semiconductor (CMOS) Image Sensors (CIS) for reactor neutrino experiments targeting coherent elastic neutrino-nucleus scattering (…

In situ cryogenic characterization of proton damage in thick p-channel skipper CCDs

Brandon M. Roach, Brenda Cervantes Vergara, Alex Drlica-Wagner +14

Skipper charge-coupled devices (CCDs) are an offshoot of standard silicon pixel detectors and are capable of performing repeated non-destructive charge measurements, enabling deepl…

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…

SENSEI: A Search for Diurnal Modulation in sub-GeV Dark Matter Scattering

Itay M. Bloch, Ana M. Botti, Mariano Cababie +28

Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth's atmosphere and crust before reaching an underground detector. This Earth-…

Investigation of Low-Energy Particle Remnants in High-Energy Collisions at the LHC with a Skipper-CCD detector

Brenda A. Cervantes-Vergara, Santiago E. Perez, Nicola Bacchetta +8

We deployed MOSKITA 33 m away from the CMS collision point, the first skipper-CCD detector probing low-energy particles produced in high-energy collisions at the Large Hadron…

Characterization of proton-induced damage in thick, p-channel skipper-CCDs

Brenda A. Cervantes-Vergara, Santiago E. Perez, Claudio R. Chavez +4

In this work, we characterize the radiation-induced damage in two thick, p-channel skipper-CCDs irradiated unbiased and at room temperature with 217-MeV protons. We evaluate the ov…
