This will be filled with liquid xenon, shielded inside a 228-ton water tank, and installed 1 mile underground in an old South Dakota gold mine. LZ will be able to test a larger range of dark matter models than any previous experiment. (I am not a member of the LZ collaboration, but most members of my research group are.)
