Project details

There is a large and convincing body of astrophysical evidence that most of the matter in the universe is dark (https://arxiv.org/pdf/1006.2483.pdf). Understanding the nature of dark matter is one of the most important problems in modern physics.

The SABRE experiment is a dark matter particle detector that is being constructed in collaboration with researchers in Australia, Europe, and the United States. To reduce the external backgrounds associated with cosmic rays, it will be housed ~1 km underground in a gold mine near Stawell in Victoria, Australia. To reduce the internal backgrounds from naturally occurring radioactive material, the detector will be fabricated from the purest NaI(Tl) scintillator material ever made. The experiment will search for an annually modulating signal due to the Earth's motion around the sun. To avoid confusion between seasonal background effects and a true dark matter signal, SABRE will operate twin detectors in the northern and southern hemisphere. A positive detection from SABRE would be an extremely important physics discovery, on par with the detection of the Higgs boson, gravitational waves, or neutrino oscillations.

The SABRE detector is a complex instrument. A rigorous understanding of its performance requires knowledge of the relevant particle/nuclear physics, detector properies, and measurement backgrounds. A Monte Carlo model of the detector has been made to investigate particle interactions with the detector, but the implementation of several aspects of this model is still preliminary. A fully validated model is a key requirement for the collaboration to understand the detector sensitivity to dark matter.

Required background
