What does it take to detect a radioactive decay event with a half-life greater than 1.3x1021 years? Find out with this engineering design challenge based on the Majorana Demonstrator housed a mile below the surface of the earth at the Sanford Underground Research Facility. Once the full-scale experiment is deployed, background signals are expected to be as low as 1 count/tonne-year.
