  • Isotopic abundance in atom trap trace analysis
    Patent number: 8674289
    Abstract: A method and system for detecting ratios and amounts of isotopes of noble gases. The method and system is constructed to be able to measure noble gas isotopes in water and ice, which helps reveal the geological age of the samples and understand their movements. The method and system uses a combination of a cooled discharge source, a beam collimator, a beam slower and magneto-optic trap with a laser to apply resonance frequency energy to the noble gas to be quenched and detected.
    Type: Grant
    Filed: February 16, 2012
    Date of Patent: March 18, 2014
    Assignee: UChicago Argonne LLC
    Inventors: Zheng-Tian Lu, Shiu-Ming Hu, Wei Jiang, Peter Mueller
