 The SABRE South Experiment at the Stawell Underground Physics Laboratory
OPENALEX - Publications 
L. J. Milligan

SABRE aims to provide a test of the signal observed by DAMA/LIBRA through two separate detectors that rely on joint ultra-high NaI(Tl) purity crystal R&D activities: South at SUPL Australia and North LNGS Italy. is designed disentangle seasonal/site-related effects from dark matter-like modulated signal. Ultra-high crystals are immersed in liquid scintillator veto, further surrounded passive shielding plastic muon veto. Significant work has been undertaken assess mitigate background detector...

Abstract In this technical design report (TDR) executive summary we describe the SABRE South detector to be built at Stawell Underground Physics Laboratory (SUPL). The is designed test long-standing DAMA/LIBRA signal of an annually modulating rate consistent with dark matter by using same target material. Located in Southern Hemisphere, uniquely positioned disentangle seasonal effects. uses seven ultra-high purity NaI(Tl) crystals (with a total mass either 35 kg or 50 kg), hermetically...

Abstract SABRE (Sodium iodide with Active Background REjection) is a direct detection dark matter experiment based on arrays of radio-pure NaI(Tl) crystals. The aims at achieving an ultra-low background rate and its primary goal to confirm or refute the results from DAMA/LIBRA experiment. Proof-of-Principle phase was carried out in 2020–2021 Gran Sasso National Laboratory (LNGS), Italy. next consists two full-scale experiments: South Stawell Underground Physics Laboratory, Australia, North...

The persistence of the DAMA/LIBRA (DAMA) modulation over past two decades has been a source great contention within dark matter community. DAMA collaboration reports persistent, modulating event rate their setup NaI(Tl) scintillating crystals at INFN Laboratori Nazionali del Gran Sasso (LNGS) underground laboratory. A recent work alluded that this signal could have arisen due to an analysis artefact, caused by not accounting for time variation decaying background radioisotopes in procedure....
