Light-tight skipper-CCDs for X-ray detection in space

Ana M. Botti, Yikai Wu, Brenda Cervantes +6

Skipper Charge-Coupled Devices (skipper-CCDs) are pixelated silicon detectors with deep sub-electron resolution. Their radiation hardness and capability to reconstruct energy depos…

SENSEI: First Direct-Detection Results on sub-GeV Dark Matter from SENSEI at SNOLAB

SENSEI Collaboration, Prakruth Adari, Itay M. Bloch +34

We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximat…
