The Search for Dark Matter

A team of Brown University researchers assembled two massive arrays of photomultiplier tubes (PMTs) for the LUX-ZEPLIN dark matter experiment, which will soon start its search for elusive dark matter particles at the Sanford Underground Research Facility in South Dakota. PMTs are powerful light sensors that can detect flashes consisting of just a few photons. The PMT arrays assembled at Brown will keep careful watch on the LZ detectors 10-ton xenon tank, looking for the tell-tale twin flashes of light produced if a dark matter particle interacts in the xenon tank.
