Description

One of the experimental techniques used for the direct detection of dark matter with noble liquids is the two-phase liquid/gas time projection chamber (TPC). In order to achieve optimal discrimination between nuclear and electron recoils in WIMP searches, large experiments have found it increasingly important to monitor continuously and precisely the detector operating conditions including liquid level, physical position, and both acoustic and electromagnetic environments. In the LUX-ZEPLIN (LZ) project, a range of monitoring sensors such as level sensors, position sensors, acoustic sensors and loop antennae will be deployed to achieve this. We report on the development of these sensors and their performance tests in the LZ system test platform constructed at SLAC.
