Dual-sided Charge-Coupled Devices
Javier Tiffenberg, Daniel Egaña-Ugrinovic, Miguel Sofo Haro +4
Existing Charge-Coupled Devices (CCDs) operate by detecting either the electrons or holes created in an ionization event. We propose a new type of imager, the Dual-Sided CCD, which…
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…
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…
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…
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…
Studies on small charge packet transport in high-resistivity fully-depleted CCDs
Miguel Sofo Haro, Guillermo Fernandez Moroni, Javier Tiffenberg
In this work, we will present a physical model and measurements of the transport of small charge packets in the bulk of thick high resistivity CCD before being collected by the pix…
The CONNIE experiment
CONNIE Collaboration, A. Aguilar-Arevalo, X. Bertou +28
The CONNIE experiment uses fully depleted, high resistivity CCDs as particle detectors in an attempt to measure for the first time the Coherent Neutrino-Nucleus Elastic Scattering…
Results of the engineering run of the Coherent Neutrino Nucleus Interaction Experiment (CONNIE)
A. Aguilar-Arevalo, X. Bertou, C. Bonifazi +25
The CONNIE detector prototype is operating at a distance of 30 m from the core of a 3.8 GW nuclear reactor with the goal of establishing Charge-Coupled Devices (CCD) as…
The DAMIC dark matter experiment
A. Aguilar-Arevalo, D. Amidei, X. Bertou +30
The DAMIC (Dark Matter in CCDs) experiment uses high resistivity, scientific grade CCDs to search for dark matter. The CCD's low electronic noise allows an unprecedently low energy…
Status of the DAMIC direct dark matter search experiment
DAMIC Collaboration, A. Aguilar-Arevalo, D. Amidei +31
The DAMIC experiment uses fully depleted, high resistivity CCDs to search for dark matter particles. With an energy threshold 50 eV, and excellent energy and spatial r…
