Welcome to SABRE South
SABRE South is a dark matter direct-detection experiment. Its goal is to search for a hypothesised type of particle which may constitute dark matter, the mysterious and elusive material that makes up about 23% of the mass-energy of the universe- around five times as much as the matter that we can see.
It will search for WIMPs (Weakly Interacting Massive Particles), one type of candidate dark matter (DM) particle. Other potential areas of investigation, utilising the experiment in parallel with its dark matter search, are being examined.
The experiment will be located deep underground in the Stawell Underground Physics Laboratory (SUPL), situated in a cavern in the Stawell Gold Mine in Victoria, Australia. Installation of equipment began in October 2023.

June 2nd, 2022 : Popular science and engineering video channel Veritasium has produced a video on the search for dark matter, featuring SABRE South and SUPL. The video excellently covers material discussed in the “Background” section of this website, as well as the experiment and lab themselves.
News
January 2026 : After much recent (and continuing) activity, progess in SUPL continues apace. The clean tent has undergone operational tests, and shows good radon reduction; PMT tests have taken place in the steel testing “coffin”; the gas control panel has been installed; the crystal glovebox has been tested.
September 2025 : A 7kg test crystal (non-Astrograde) has arrived in Melbourne from SICCAS. The main clean room (to be used for crystal qualification, and crystal module assembly) has been put together in SUPL.
August 2025 : The Crystal Insertion System frame and glovebox, the crystal module assembly glovebox, and a dry box have been delivered to SUPL. A small clean tent has been assembled, and tests indicate that a good radon concentration of around 12 Bq/m3 is maintained within. Steel plates for the main vessel shielding fabrication has arrived at Thornton’s.
April 2025 : The SABRE collaboration has published The SABRE South technical design report executive summary, an in-depth description of the design and expected performance of the SABRE South experiment.
April 2024 : The ANU has developed a virtual 3D tour of SUPL and Wantirna. It may be explored here.
