CMOS Image Sensors for CEvNS Detection at Nuclear Reactors
Santiago Ezequiel Perez, Dario Rodrigues, Miguel Sofo-Haro
In this work we present Complementary Metal-Oxide-Semiconductor (CMOS) Image Sensors (CIS) for reactor neutrino experiments targeting coherent elastic neutrino-nucleus scattering (…
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 ($…
A Sub-electron-noise Skipper-CCD Readout ASIC with Improved Channel-to-channel Isolation and an Integrated Cryogenic Voltage Reference
Fabricio Alcalde Bessia, Claudio Chavez, Troy England +6
The MIDNA application specific integrated circuits (ASICs) are a series of skipper-CCD readout chips fabricated in a 65 nm low-power CMOS process that implement a correlated double…
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…
Achieving Single-Electron Sensitivity at Enhanced Speed in Fully-Depleted CCDs with Double-Gate MOSFETs
Miguel Sofo-Haro, Kevan Donlon, Juan Estrada +3
We introduce a new output amplifier for fully-depleted thick p-channel CCDs based on double-gate MOSFETs. The charge amplifier is an n-type MOSFET specifically designed and operate…
Skipper-CCD Sensors for the Oscura Experiment: Requirements and Preliminary Tests
Brenda A. Cervantes-Vergara, Santiago Perez, Juan Estrada +52
Oscura is a proposed multi-kg skipper-CCD experiment designed for a dark matter (DM) direct detection search that will reach unprecedented sensitivity to sub-GeV DM-electron intera…
Photon counting from the vacuum ultraviolet to the short wavelength infrared using semiconductor and superconducting technologies
Jonathan Asaadi, Dan Baxter, Karl K. Berggren +27
In the last decade, several photon counting technologies have been developed opening a new window for experiments in the low photon number regime. Several ongoing and future projec…
Single-electron and single-photon sensitivity with a silicon Skipper CCD
Javier Tiffenberg, Miguel Sofo-Haro, Alex Drlica-Wagner +5
We have developed a non-destructive readout system that uses a floating-gate amplifier on a thick, fully depleted charge coupled device (CCD) to achieve ultra-low readout noise of…
