A Test Bed for LZ Photomultiplier Tubes (PMTs) (image) DOE/Lawrence Berkeley National Laboratory Share Print E-Mail Caption 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.
