LUX-ZEPLIN Skin Detector Performance
ORAL
Abstract
LUX-ZEPLIN (LZ) is a dark matter experiment located at the Sanford Underground Research Facility in South Dakota, USA. LZ consists of a dual-phase xenon time projection chamber (TPC) and two active veto systems: a Skin detector and an Outer Detector. The Skin detector contains approximately 2 tonnes of liquid xenon instrumented with 131 photomultiplier tubes. This xenon Skin surrounds the central TPC and functions primarily to identify gamma-ray induced backgrounds and internal backgrounds with correlated gamma-ray emission. This talk will cover the energy and position calibrations, liquid flow patterns, and veto performance of the LZ Skin detector.
