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…

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-…
