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…
MAS-CCD: New technique for measuring low-level charge content based on the multiple amplifier architecture
Miqueas E. Gamero, Guillermo Fernández Moroni, Fernando Chierchie +4
Low-noise detectors are a key technology for the next generation of astronomical instruments aimed at spectroscopy of faint objects and the search for exoplanets. In this context,…
Characterization of proton-induced damage in thick, p-channel skipper-CCDs
Brenda A. Cervantes-Vergara, Santiago E. Perez, Claudio R. Chavez +4
In this work, we characterize the radiation-induced damage in two thick, p-channel skipper-CCDs irradiated unbiased and at room temperature with 217-MeV protons. We evaluate the ov…
Towards a quantum realization of the ampere using single-electron resolution Skipper-CCDs
Miqueas Gamero, Agustin Lapi, Blas Irigoyen Gimenez +7
This paper presents a proof-of-concept demonstration of the Skipper-CCD, a sensor with single-electron counting capability, as a promising technology for implementing an electron-p…
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…
First results from a multiplexed and massive instrument with sub-electron noise Skipper-CCDs
F. Chierchie, C. R. Chavez, M. Sofo Haro +7
We present a new instrument composed of a large number of sub-electron noise Skipper-CCDs operated with a two stage analog multiplexed readout scheme suitable for scaling to thousa…
Analog pile-up circuit technique using a single capacitor for the readout of Skipper-CCD detectors
Miguel Sofo Haro, Claudio Chavez, Jose Lipovetzky +8
With Skipper-CCD detectors it is possible to take multiple samples of the charge packet collected on each pixel. After averaging the samples, the noise can be extremely reduced all…
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…
Smart-readout of the Skipper-CCD: Achieving Sub-electron Noise Levels in Regions of Interest
Fernando Chierchie, Guillermo Fernandez Moroni, Leandro Stefanazzi +7
The skipper CCD is a special type of charge coupled device in which the readout noise can be reduced to sub-electron levels by averaging independent measurements of the same charge…
