Skipper-CCD Sensors for the Oscura Experiment: Requirements and Preliminary Tests
Brenda A. Cervantes-Vergara, Santiago Perez, Juan Estrada +52
Oscura is a proposed multi-kg skipper-CCD experiment designed for a dark matter (DM) direct detection search that will reach unprecedented sensitivity to sub-GeV DM-electron intera…
Background Rejection in Highly Pixelated Solid-State Detectors
Alvaro E. Chavarria
Highly pixelated solid-state detectors offer outstanding capabilities in the identification and suppression of backgrounds from natural radioactivity. We present the background-ide…
Snowmass 2021 White Paper: The Selena Neutrino Experiment
A. E. Chavarria, C. Galbiati, B. Hernandez-Molinero +8
Imaging devices made from an ionization target layer of amorphous selenium (aSe) coupled to a silicon complementary metal-oxide-semiconductor (CMOS) active pixel array for charge r…

Imaging sensors made from an ionization target layer of amorphous selenium (aSe) coupled to a silicon complementary metal-oxide-semiconductor (CMOS) active pixel array for charge r…
Measurement of the ionization response of amorphous selenium with 122keV rays
Xinran Li, Alvaro E. Chavarria, Snezana Bogdanovich +3
We performed a measurement of the ionization response of 200 m-thick amorphous selenium (aSe) layers under drift electric fields of up to 50 V/m. The aSe target was exposed t…
Measurement of the bulk radioactive contamination of detector-grade silicon with DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, D. Baxter +28
We present measurements of bulk radiocontaminants in the high-resistivity silicon CCDs from the DAMIC at SNOLAB experiment. We utilize the exquisite spatial resolution of CCDs to d…
