Description
The LUX-ZEPLIN (LZ) experiment set world-leading limits for spin-independent WIMP-nucleon interactions above 10 GeV/$c^2$, with its first science run results released in 2022. Background characterisation and a complete understanding of the detector and internal conditions is vital to achieve and improve upon such limits; in the chance of discovery, these are a necessity to provide a foundation for the result. LZ utilises a dual-phase time projection chamber (TPC) with 7 tonnes of active xenon to generate and image signals within the detector. Acoustic sensors; loop antennae; and weir-level sensors were developed and installed on the detector to monitor the vibrational and electromagnetic environments as well as detect the presence of any surface waves within the TPC.
I will showcase the first studies into monitoring the internal conditions of the TPC using these sensors, including any correlations found between these conditions and backgrounds observed.
