The LUX-Zeplin (LZ) experiment is a WIMP detector. The international collaboration constructing it formed in 2012 by combining the LUX and ZEPLIN groups. It is to be located at the Sanford Underground Research Facility (SURF) in South Dakota, and managed by DOE’s Lawrence Berkeley National Lab (Berkeley Lab). The LZ experiment is a next-generation dark matter direct detection experiment. When completed, the experiment will be the world’s most sensitive experiment for WIMPs (Weakly Interacting Massive Particles) over a large range of WIMP masses In the spring of 2015, LZ passed the ‘Critical Decision Step 1’ or CD-1 review, and became an official DOE project. As of May 2021, the detector is being commissioned.
