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…
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…
Low Threshold Acquisition controller for Skipper CCDs
Gustavo Cancelo, Claudio Chavez, Fernando Chierchie +10
The development of the Skipper Charge Coupled Devices (Skipper-CCDs) has been a major technological breakthrough for sensing very weak ionizing particles. The sensor allows to reac…
SENSEI: Direct-Detection Results on sub-GeV Dark Matter from a New Skipper-CCD
Liron Barak, Itay M. Bloch, Mariano Cababie +20
We present the first direct-detection search for eV-to-GeV dark matter using a new ~2-gram high-resistivity Skipper-CCD from a dedicated fabrication batch that was optimized for da…
