Light-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)

A 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.
Two of the photomultiplier tubes to be used in the LZ experiment. These are capable of detecting a single photon, they operate at -108 Celsius, and they have an extremely tiny quantity of natural radioactivity in their components.
