    Research Highlights: Recent Low Concentration Measurements

    Posted on January 27, 2022
    We have been testing the performace and sensitivity limits of BioXAS-Spectroscopy Main. Including Se 115 ppm K-edge EXAFS measurement of NIST 611 Sub ppm measurements on solid sample:  Au L3 edge - 500 ppb 1 ppm Eu XANES on NIST 614 standard Standard:   We are excited about these measurements! Please contact beamline staff to discuss the sensitivity for your experiments!  

  • : BioXAS Fall shutdown Update

    Posted on November 16, 2020
    Many improvements to the storage ring and beamlines are happening during the fall shutdown at the CLS. At BioXAS, engineers and technicians are installing a new air conditioning system to keep the optical elements, detectors, and electronics operating within their optimal temperature ranges. This will increase beam stability and improve the detector signal to noise ratio. The work will be completed for the start of cycle 33 in January 2021. Pictures of the AC installation
