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…

Characterization of Spurious Charge in SENSEI Skipper-CCDs

Yikai Wu, Ansh Desai, Sho Uemura +16

Skipper Charge-Coupled Devices (Skipper-CCDs) are a leading technology in the search for sub-GeV dark matter and coherent elastic neutrino-nucleus scattering. A key background for…

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-…

SENSEI: First Direct-Detection Results on sub-GeV Dark Matter from SENSEI at SNOLAB

SENSEI Collaboration, Prakruth Adari, Itay M. Bloch +34

We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximat…
