    Facilities

    CHESS has proposed that the NSF support a “sub-facility” at CHESS. This allows other federal and state agencies, private foundations, academic institutions, and private industry to become partners with CHESS.

50 years Later, Wilson Lab stays cutting edge 
This October marks the 50th anniversary of the dedication of the Wilson Synchrotron Laboratory. Initially built for $11million and promising to deliver cutting-edge research in elementary particle physics, it was the NSF’s largest project at that time. Fifty years later, the lab is going through its biggest upgrade in decades.

Read 1000 BC Middle East gypsum tablet with X-ray fluorescence
Many ancient inscriptions on stones have been worn and weathered, and the original text is no longer visible. Scanning X-ray fluorescence (SXRF) imaging of chemical tracing elements on epigraphy has been used to significantly improve the legibility of heavily weathered and worn stone surfaces.
