XENON合作旨在直接探测弱相互作用大质量粒子（WIMPs）形式的冷暗物质。用一个充满液态氙的双相时间投影室来探测WIMP与核子的相互作用。对于下一代实验XENON1T，其有效目标质量为1吨氙，在明斯特大学核物理研究所设计并测试了一个新的蒸馏塔，用于从氙中去除氪，使氙中的天然氪浓度< 5 × 10−13（0.5 ppt）。实验装置连同两个诊断工具，以及一个稳定性测试的11小时的蒸馏运行在3公斤每小时的设计流量。
The XENON collaboration aims for the direct detection of cold dark matter in form of weakly interacting massive particles (WIMPs). A dual phase time projection chamber filled with liquid xenon is used to detect the WIMP-nucleon interaction. For the next generation experiment XENON1T with an active target mass of 1 ton of xenon, a new distillation column to remove krypton out of xenon to a concentration of < 5 × 10−13 (0.5 ppt) natural krypton in xenon is designed and tested at the Institut für Kernphysik, Universitat Munster. The experimental setup together with two diagnostic tools is presented, as well as one stability test of a 11 hour distillation run at the designed flowrate of 3 kg per hour.
