Opening after CHESS-U! Employees beyond the lab, Science Highlights, and more
From the Associate Director
Tomorrow, Oct. 16th, CHESS resumes user operations with an upgraded and transformed facility: The energy of the stored beam was raised from 5.3GeV to 6.0GeV, the beam emittance is significantly reduced and we plan to gradually increase the stored current from around 100mA to 200mA over the next year. Seven new experimental systemsincluding x-ray optics, experimental hutches, safety systems, and control systems were installed on the reconfigured CHESS experimental floor and are now available to users. Each experimental station is fed by its own Cornell compact undulator based on an innovative approach originally developed by A. Temnykh here at CHESS and featured in this newsletter.
Our series “Beyond the Lab” profiles Kurt McDonald this month. As CHESS operator, Kurt ensures that CHESS equipment operates perfectly and user experiments are successful as possible. Outside the lab, as co-owner and brewing master of Summerhill Brewing, Kurt creates tasty craft beers that local customers as well as tourists traveling through the area enjoy immensely.
Looking ahead, CHESS is now accepting proposals for the January to March 2020 cycle. Important information about CHESS beamlines and capabilities can be found in the Beamline Directory. Submitting a general user proposal is the most common way for users to access a beamline. Users can also submit a beamtime request (BTR)for a proposal that was submitted in the previous cycle. Our “New User Guide” with important information on the proposal submission and review process can be found here.
While a lot has changed here at CHESS over the past year, some important things stay the same: CHESS will continue to educate and train the next generation of scientists, develop cutting edge x-ray technologies, and support world-class X-ray science.
This October, the new user facilities at the Cornell High-Energy Synchrotron Source (CHESS) will open their doors to researchers. This opening follows a major upgrade project, known as CHESS-U, which establishes CHESS as one of the world’s leading X-ray sources.
Researchers at CHESS are working to improve the already impressive CHESS Compact Undulator, or CCU. Within the new NSF-funded CHEXS award, Sasha Temnykh is developing the driving mechanisms that will allow for variable gap control and better tuning of the device, resulting in higher magnetic fields and more overall flux; both desirable qualities for a variety of experimental needs.
Beyond the Lab with Kurt McDonald: CHESS Operator:As a CHESS operator, Kurt McDonald has a full time job. As an integral part of the daily functions of the lab, Kurt’s position involves working with scientists, engineers, and CHESS technical staff to provide visiting researchers with the resources that they need.
