Tritium production in SuperCDMS Silicon detectors

ORAL

Abstract

The SuperCDMS experiment will utilize germanium (Ge) and silicon (Si) detectors to detect interactions from low-mass dark matter particles. Cosmic-ray interactions can produce tritium, a long-lived radioactive isotope, that can produce background events in the detectors. I present the processes that produce tritium in silicon aboveground and underground locations and describe the exposure history of the SuperCDMS silicon detectors and the efforts to mitigate tritium production. Finally, I present my calculation of the expected tritium production in the detectors.
