From the Director
Joel Brock
The spread of the coronavirus (COVID-19) is evolving rapidly and Cornell University officials are proactively working with local and state public health organizations to protect the health and well-being of the community.

To implement the Cornell policy regarding “COVID-19 Update: Conduct of Research”, CHESS user operations ended at noon on Monday, March 16th, 2020. User experiments at CHESS scheduled for March 2020 will not take place. We do not know when CHESS will be able to resume operations. Beamtime allocations for the May/June 2020 cycle will not be made until the schedule for the resumption of user operations is known.

We will continue to provide additional information about CHESS user operations on this CHESS web page , please check back often for updates. 

Despite the impact of the coronavirus, there are many positive developments here at CHESS:

Careful optimization of storage ring parameters and beamline performance, allowed us to increase the ring current during user operations from 50mA to 75 mA on Feb. 18th and now to 100mA on March 11th . Congratulations to everyone for achieving this milestone! Further increases require detailed radiation surveys to ensure personnel safety in the CHESS user area and will begin as we return to operations.

Beginning in September 2019, the National Science Foundation (NSF) supports the operation of the Center for High Energy X-ray Sciences (CHEXS) at the Cornell High Energy Synchrotron Source (CHESS) as a national user facility. The first research articles that were supported by NSF through CHEXS can be found here.

As we continues to address the impact of the coronavirus on our facility and community, please know that we work continuously with our staff and users to operate CHESS in the safest and most effective way possible. Please take care of yourself and one another.
