PMTs LBL21417Light-amplifying devices known as photomultiplier tubes (PMTs), developed for use in the LUX-ZEPLIN (LZ) dark matter-hunting experiment, are prepared for a test at Brown University. This test bed, dubbed PATRIC, will be used to test over 600 PMTs in conditions simulating the temperature and pressure of the liquid xenon that will be used for LZ. (Credit: Brown University)

Scintillator fluid will surround LZ’s xenon tank and will help scientists veto the background “noise” of unwanted particle signals. (Credit: Brookhaven National Laboratory)

The LZ water shield, currently housing the LUX experimentA fish-eye view of the water tank where the LUX detector was deployed, and where the LZ detector will be deployed.   The diameter of the tank is 25 feet, the height 20 feet, and it is filled with highly purified water.
