SUMMARY:Dark Matter direct detection at the Stawell Underground Physics Laboratory
DESCRIPTION:The Stawell Underground Physics Laboratory (SUPL) is a newly built underground facility in regional Victoria\, Australia. The laboratory is be located 1024 m underground (~2900 m water equivalent) within the Stawell Gold Mine and its construction has been completed in 2022/2023. The laboratory will house rare event physics searches\, including the upcoming SABRE South dark matter experiment\, as well as measurement facilities to support low background physics experiments and applications such as radiobiology and quantum computing. SABRE South will be the first experiment assembled in SUPL and its commissioning is expected to occur in 2023/2024. SABRE South is part of the SABRE experiment which aims to detect an annual rate modulation from dark matter interactions in ultra-high purity NaI(Tl) crystals in order to provide a model independent test of the signal observed by DAMA/LIBRA. SABRE South has different shielding design than SABRE North and it is designed to disentangle seasonal or site-related effects from the dark matter-like modulated signal by using an active veto and muon detection system.  Ultra-high purity NaI(Tl) crystals are immersed in a linear alkyl benzene (LAB) based liquid scintillator veto\, further surrounded by passive steel and polyethylene shielding and a plastic scintillator muon veto. Significant work has been undertaken to understand and mitigate the background processes\, that take into account radiation from the detector materials\, from both intrinsic and cosmogenic activated processes\, and to understand the performance of both the crystal and veto systems. This talk will report on the design of SUPL and on the status of the SABRE South assembly.
