Characterization of the Cherenkov Photon Background for Low-Noise Silicon Detectors in Space

Manuel E. Gaido, Javier Tiffenberg, Alex Drlica-Wagner +7

Future space observatories that seek to perform imaging and spectroscopy of faint astronomical sources will require ultra-low-noise detectors that are sensitive over a broad wavele…

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…
