Distillation of Liquid Xenon to Remove Krypton
arXiv:0809.4413 · doi:10.1016/j.astropartphys.2009.02.006
Abstract
A high performance distillation system to remove krypton from xenon was constructed, and a purity level of Kr/Xe = was achieved. This development is crucial in facilitating high sensitivity low background experiments such as the search for dark matter in the universe.
