Cornell High Energy Synchrotron Source (CHESS) is a high-intensity X-ray source supported by the National Science Foundation which provides our users state-of-the-art synchrotron radiation facilities for research in Physics, Chemistry, Biology, and Environmental and Materials Sciences.
A special NIH Research Resource, called MacCHESS, supports special facilities for macromolecular crystallography and BioSAXS. CHESS-U is the current upgrade that will extend CHESS’s capacity for cutting edge research.
- CHESS was constructed in the period from 1978 to 1980 as a synchrotron x-ray facility parasitic to the CESR High Energy Physics program.
- At the completion of CHESS-U in 2018, CHESS will be the premier synchrotron source in the US for high-energy, high-flux x-ray studies.
