Studying single-electron traps in newly fabricated Skipper-CCDs for the Oscura experiment using the pocket-pumping technique
S. E. Perez, B. A. Cervantes-Vergara, J. Estrada +3
Understanding and characterizing very low-energy (eV) background sources is a must in rare-event searches. Oscura, an experiment aiming to probe electron recoils from sub-GeV…
Unraveling Fano noise and partial charge collection effect in X-ray spectra below 1 keV
Dario Rodrigues, Mariano Cababie, Ignacio Gomez Florenciano +6
Fano noise, readout noise, and the partial charge collection (PCC) effect collectively contribute to the degradation of energy spectra in Charge Coupled Devices (CCD) measurements,…
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…
Infrared photon-number-resolving imager using a Skipper-CCD
Q. Pears Stefano, A. G. Magnoni, J. Estrada +3
Imaging in a broad light-intensity regime with a high signal-to-noise ratio is a key capability in fields as diverse as Quantum Metrology and Astronomy. Achieving high signal-to-no…
Photon counting from the vacuum ultraviolet to the short wavelength infrared using semiconductor and superconducting technologies
Jonathan Asaadi, Dan Baxter, Karl K. Berggren +27
In the last decade, several photon counting technologies have been developed opening a new window for experiments in the low photon number regime. Several ongoing and future projec…
Constraints on the electron-hole pair creation energy and Fano factor below 150 eV from Compton scattering in a Skipper-CCD
A. M. Botti, S. Uemura, G. Fernandez Moroni +9
Fully-depleted thick silicon Skipper-charge-coupled devices (Skipper-CCDs) are an important technology to probe neutrino and light-dark-matter interactions due to their sub-electro…
SENSEI: Characterization of Single-Electron Events Using a Skipper-CCD
Liron Barak, Itay M. Bloch, Ana Botti +22
We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the orig…
Charge collection efficiency in back-illuminated Charge-Coupled Devices
Guillermo Fernandez-Moroni, Kevin Andersson, Ana Botti +3
Low noise CCDs fully-depleted up to 675 micrometers have been identified as a unique tool for Dark Matter searches and low energy neutrino physics. The charge collection efficiency…
Absolute measurement of the Fano factor using a Skipper-CCD
Dario Rodrigues, Kevin Andersson, Mariano Cababie +11
Skipper-CCD can achieve deep sub-electron readout noise making possible the absolute determination of the exact number of ionized electrons in a large range, from 0 to above 1900 e…
