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 data acquisition and triggering system is a critical component of the experiment. The ANU is contributing to the development of the SABRE DAQ and will replicate some of the state-of-the-art digitizer hardware to run experiments locally and as a backup for SABRE. The DAQ needs to be implemented, validated, and optimised to handle as high of an event rate as possible. Ensuring data integrity is also a key consideration.
Students with coding and/or signal processing experience are encouraged to apply.
Students should be willing to attend phone meetings with collaborators in Australia and overseas.
