Constraints on Sub-MeV Dark Matter from Solar Reflection with DAMIC-M
K. Aggarwal, I. Arnquist, N. Avalos +41
The Sun acts as a natural dark matter accelerator. Galactic halo particles scattering in the solar plasma emerge with velocities well beyond the Galactic escape speed, providing a…
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 (…
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…
Daily Modulation Constraints on Light Dark Matter with DAMIC-M
K. Aggarwal, I. Arnquist, N. Avalos +40
The flux of Hidden Sector particles from the Galactic halo reaching an underground detector can be significantly attenuated by interactions within the Earth for sufficiently large…
First Production of Skipper-CCD Modules for the DAMIC-M Experiment
H. Lin, M. Traina, S. Paul +65
The DAMIC-M experiment will search for sub-GeV dark matter particles with a large array of silicon skipper charge-coupled devices (CCDs) at the Modane Underground Laboratory (LSM)…
