Description
SABRE is an international collaboration that will operate similar particle de-
tectors in the Northern (SABRE North) and Southern Hemispheres (SABRE
South). This innovative approach distinguishes possible dark matter signals
from seasonal backgrounds, a pioneering strategy only possible with a southern
hemisphere experiment. SABRE South is located at the Stawell Underground
Physics Laboratory (SUPL), in regional Victoria, Australia.
SUPL is a newly built facility located 1024 m underground (∼2900 m water
equivalent) within the Stawell Gold Mine and its construction has been com-
pleted in 2023.
SABRE South employs ultra-high purity NaI(Tl) crystals immersed in a Linear
Alkyl Benzene (LAB) based liquid scintillator veto, enveloped by passive steel
and polyethylene shielding alongside a plastic scintillator muon veto. Signifi-
cant progress has been made in the procurement, testing, and preparation of
equipment for installation of SABRE South. The SABRE South muon detector
and the data acquisition systems are actively collecting data at SUPL and the
SABRE South’s commissioning is planned to be completed by the end of 2025.
This presentation will provide an update on the overall progress of the SABRE
South construction, its anticipated performance, and its potential physics reach.
