In situ cryogenic characterization of proton damage in thick p-channel skipper CCDs
Brandon M. Roach, Brenda Cervantes Vergara, Alex Drlica-Wagner +14
Skipper charge-coupled devices (CCDs) are an offshoot of standard silicon pixel detectors and are capable of performing repeated non-destructive charge measurements, enabling deepl…
X-ray Response of the Fully-Depleted, p-Channel SiSeRO-CCD
Julian Cuevas-Zepeda, Joseph Noonan, Claudio Chavez +6
We present an X-ray characterization of a fully depleted, 725 m thick p-channel SiSeRO-CCD. Measurements with a Fe source yield an energy resolution of eV (…
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…
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…
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…
Automating Sensor Characterization with Bayesian Optimization
J. Cuevas-Zepeda, C. Chavez, J. Estrada +6
The development of novel instrumentation requires an iterative cycle with three stages: design, prototyping, and testing. Recent advancements in simulation and nanofabrication tech…
