An atom trap trace analysis (ATTA) system for measuring ultra-low contamination by krypton in xenon dark matter detectors
… nuclei within its liquid xenon (LXe) target. The trace 85Kr in the xenon target undergoes beta-decay with a 687 keV end point and 10.8 year halflife, which contributes background events and limits the sensitivity of the experiment. In order to achieve the desired sensitivity, the contamination by …

Fabrication of an Apparatus for All-Optical Production of Metastable Krypton
<p>Atom Trap Trace Analysis (ATTA) has made radiokrypton dating of polar ice and groundwater samples a possibility for scientists all over the world, allowing them to date samples further back in time and more accurately than other methods. However, this technique is hampered by the 36-hour …
