New Experimental Hall - Construction Continues
As many inhabitants of Wilson lab have heard, seen, smelled, and felt, the New Experimental Hall (NEH) civil construction project is full speed ahead.
Welcome Jeney Wierman - New MacCHESS Director
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.
Summer 2022 Undergraduate Students at CHESS
The Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE) funds summer research opportunities in the areas of x-ray and accelerator sciences, materials science, chemistry, and mechanical engineering for pre-selected undergraduate students from primarily undergraduate institutions and minority serving institutions. Approximately a dozen REU (Research Experiences for Undergraduates) students each summer are hosted by CLASSE. Students from the CHESS summer programs -- SERCCS, PREM, and SUNRiSE -- are midway through their summer undergraduate research experience.
New, diverse users get firsthand experience at HEXT workshop
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.
Intermediate Valence State in YbB4 Revealed by Resonant X-ray Emission Spectroscopy
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.
Dynamics of Recrystallized Grains in a Hot-Compressed Mg-Zn-Ca Alloy
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. These alloys have potential to make vehicles lighter and reduce greenhouse gases.
Students of Puerto Rico Designing Techniques of HMF at CHESS
The Cornell High Energy Synchrotron Source, CHESS, and the University of Puerto Rico are continuing a collaboration that will shape the future of the synchrotron X-Ray laboratory as it builds the new High Magnetic Field facility, HMF.
Characterization of 128 x 128 MM-PAD-2.1 ASIC: a Fast Framing Hard X-ray Detector with High Dynamic Range
Hybrid pixel array detectors (PADs) have proven to be powerful, versatile area detectors for X-ray science. A new prototype would enable significant advances in time-resolved studies of dynamic phenomena.
