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…
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…
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 ($…
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…
SENSEI: A Search for Diurnal Modulation in sub-GeV Dark Matter Scattering
Itay M. Bloch, Ana M. Botti, Mariano Cababie +28
Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth's atmosphere and crust before reaching an underground detector. This Earth-…
A compact, low-power epithermal neutron counter for lunar water detection
Julian Cuevas-Zepeda, Phoenix Alpine, Brenda A. Cervantes-Vergara +7
The detection and characterization of lunar water are critical for enabling sustainable human and robotic exploration of the Moon. Orbital neutron spectrometers, such as instrument…
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…
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…
DarkNESS: developing a skipper-CCD instrument to search for Dark Matter from Low Earth Orbit
Phoenix Alpine, Samriddhi Bhatia, Fernando Chierchie +8
The DarkNESS (Dark Matter Nano-satellite Equipped with Skipper Sensors) mission aims to deploy a skipper-CCD CubeSat Observatory to search for dark matter (DM) from Low Earth Orbit…
SENSEI at SNOLAB: Single-Electron Event Rate and Implications for Dark Matter
Itay M. Bloch, Ana M. Botti, Mariano Cababie +27
We present results from data acquired by the SENSEI experiment at SNOLAB after a major upgrade in May 2023, which includes deploying 16 new sensors and replacing the copper trays t…
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…
