Jeney Wierman started as the new MacCHESS Director on July 1st, 2022.  Below is a welcome message to the whole CHESS Community. Jeney takes over the MacCHESS directorship from Marian Szebenyi, who will be retiring later this year after 30 years at MacCHESS.

The High Energy X-ray Techniques (HEXT) workshop took place in late May, giving students the knowledge and skills to plan, conduct, and interpret synchrotron experiments, answering questions specific to their research interests in material science.

CHEXS users have directly observed an electronic configuration that is quantum mechanically mixed between the Yb2+ and Yb3+ valence states in the material YbB4. These observations confirm an “intermediate valence” conjecture for this material, which was first hypothesized 50 years ago.

Recent research performed at CHESS presents new insights into the microstructural evolution which occurs during annealing of Mg alloys using in-situ X-ray diffraction.

At the CHESS User Meeting, we recognized the best student paper and outstanding poster presentations based on research performed at CHESS during the past year.

Congratulations to Ashley Bucsek and Kushol Gupta!

Attend the meeting for updates on all CHESS facilities, science talks from CHESS researchers, and to network during breaks and the poster session.

The CHESS Users’ Meeting will be held in-person at the Physical Sciences Building at Cornell, with the option to view the meeting online via Zoom.

This workshop will identify forefront research opportunities for optical control of physical properties in biological, chemical, and materials systems.

Today, 60 feet below the Cornell University campus, at the Cornell High Energy Synchrotron Source (CHESS), researchers utilize X-rays that are 100 million times more intense than Röntgen's first beams of light.
