Descrição: We report on the radon emanation rate and xenon purification performance of hot zirconium getters, with a focus on their application to the LUX-ZEPLIN (LZ) dark matter experiment. New radon emanation measurements and HPGe gamma screening measurements of the getter pills and their precursor materials are presented, along with the performance of the ‘Megatorr’ purifier employed by LZ to remove electronegatives and other impurities from its Xe inventory.
