2015 arXiv   pre-print
The design and performance of the LUX-ZEPLIN (LZ) detector is described as of March 2015 in this Conceptual Design Report.  ...  LZ is a second-generation dark-matter detector with the potential for unprecedented sensitivity to weakly interacting massive particles (WIMPs) of masses from a few GeV/c2 to hundreds of TeV/c2.  ...  OSHA flammable and combustible liquid regulations do not apply to IIIB liquids. The boiling point is greater than 250 °C, and the melting point is below -70 °C, so it is very stable as a liquid.  ...
