The Cornell High Energy Synchrotron Source, CHESS, is a high-intensity X-ray source which provides its users state-of-the-art synchrotron radiation facilities for research in Physics, Chemistry, Biology, and Environmental and Materials Sciences. CHESS has undergone a monumental upgrade that has rebuilt the laboratory. CHESS-U will provide even more undulator beamtime availability for individual user groups to develop new instruments, new techniques, and new applications for synchrotron radiation.
