X-ray characterization of fully-depleted p-channel Skipper-CCDs for the DarkNESS mission
Phoenix Alpine, Ana M. Botti, Brenda A. Cervantes-Vergara +11
The Dark matter Nanosatellite Equipped with Skipper Sensors (DarkNESS) mission is a 6U CubeSat designed to search for X-ray lines from decaying dark matter using Skipper-CCDs. Thic…
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…
DarkNESS: A skipper-CCD NanoSatellite for Dark Matter Searches
Phoenix Alpine, Samriddhi Bhatia, Ana M. Botti +16
The Dark matter Nanosatellite Equipped with Skipper Sensors (DarkNESS) deploys a recently developed skipper-CCD architecture with sub-electron readout noise in low Earth orbit (LEO…
Readout Optimization of Multi-Amplifier Sensing Charge-Coupled Devices for Single-Quantum Measurement
Ana M. Botti, Brenda A. Cervantes-Vergara, Claudio R. Chavez +15
The non-destructive readout capability of the Skipper Charge Coupled Device (CCD) has been demonstrated to reduce the noise limitation of conventional silicon devices to levels tha…
Astronomical Spectroscopy with Skipper CCDs: First Results from a Skipper CCD Focal Plane Prototype at SIFS
Edgar Marrufo Villalpando, Alex Drlica-Wagner, Brandon Roach +22
We present the first on-sky results from an ultra-low-readout-noise Skipper CCD focal plane prototype for the SOAR Integral Field Spectrograph (SIFS). The Skipper CCD focal plane c…
Characterization and Optimization of Skipper CCDs for the SOAR Integral Field Spectrograph
Edgar Marrufo Villalpando, Alex Drlica-Wagner, Andrés A. Plazas Malagón +14
We present results from the characterization and optimization of six Skipper CCDs for use in a prototype focal plane for the SOAR Integral Field Spectrograph (SIFS). We tested eigh…
