Cosmogenic activation in detector materials at shallow depths
Sagar S. Poudel, Lekhraj Pandey, Robert Calkins +6
The radioactive decay from long-lived radioactive isotopes produced by cosmogenic activation can be an important background in direct-detection dark matter and neutrino experiments…
Search for low-mass electron-recoil dark matter using a single-charge sensitive SuperCDMS-HVeV Detector
SuperCDMS Collaboration, M. F. Albakry, I. Alkhatib +146
We present constraints on low-mass dark matter electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken undergr…
Low-Energy Calibration of SuperCDMS HVeV Cryogenic Silicon Calorimeters Using Compton Steps
SuperCDMS Collaboration, M. F. Albakry, I. Alkhatib +148
Cryogenic calorimeters for low-mass dark matter searches have achieved sub-eV energy resolutions, driving advances in both low-energy calibration techniques and our understanding o…
Multi-channel, multi-template event reconstruction for SuperCDMS data using machine learning
M. F. Albakry, I. Alkhatib, D. Alonso-Gonzalez +139
SuperCDMS SNOLAB uses kilogram-scale germanium and silicon detectors to search for dark matter. Each detector has Transition Edge Sensors (TESs) patterned on the top and bottom fac…
Applying Geant4's Importance Biasing to improve the efficiency of SuperCDMS background simulations
B. Zatschler, A. J. Biffl, R. Calkins +6
Experiments searching for extremely rare events surround their sensitive detectors with several layers of different shielding materials to protect them from external radiation and…
