ZEPLIN II is a two‐phase xenon detector designed to detect dark matter in the form of Weakly Interacting Massive Particles (WIMPs). Following the first 31‐day underground run in Boulby Mine, UK, the collaboration published dark matter limits in January 2007; the first such limits using two‐phase xenon technology. We outline the key detector design, performance and results here.
