is located at Cornell University in Ithaca, NY

CHESS website

The Cornell High Energy Synchrotron Source is a high-intensity high-energy X-ray source supported by the National Science Foundation. CHESS 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 protein crystallographic studies. CHESS serves a wide spectrum of experimental groups from Universities, National Laboratories and Industry.

About Structural Biology at CHESS

macchess_logo.gif Macromolecular Diffraction Facility at the Cornell High Energy Synchrotron Source (MacCHESS)
The National Institutes of Health (NIH), through its National Center for Research Resources (NCRR), funds MacCHESS for two purposes: core research and suport of CHESS users, who perform macromolecular diffraction experiments. MacCHESS staff conduct research in the areas of cell signaling, micro diffraction, membrane proteins, optimized data collection at synchrotron sources, crystallographic phasing, large unit cell crystallography, x-ray optics for crystallography and other areas relevant to macromolecular crystallography. On the user support front, the facility makes available specialized equipment and expertise, in addition to those provided by CHESS to all users. MacCHESS staff provide training and advice in the use of all these amenities. Guidance in determining MacCHESS's major emphases is provided by the MacCHESS Advisory Committee.
