Alongside enormous construction project, CHESS restarts to deliver beam to users.
Researchers have returned to CHESS this month after a long summer of construction and upgrades to the facility. CHESS shuts down yearly to allow for machine upgrades and to beat the heat and humidity of summer, but starting back up is never as easy as "flipping on a switch."
The influence of alloying on slip intermittency and the implications for dwell fatigue in titanium
The high precision of HEDM measurements at FAST offer new insight into the microscopic processes that cause dwell fatigue, pointing toward new alloying strategies for mitigation.
Turning Heroic Efforts Into Everyday Experiments
Driven by the insights from 3D data acquired in real-time, the creation of new characterization methods for structural metals has seen explosive growth over the past two decades. Using high-energy X-rays and new generations of detectors, like those available at CHESS, scientists can now extract higher-resolution information over larger volumes of material at rates that were only a dream several years ago
A New Robotic Arm at the Structural Materials Beamline
A new Kuka Robotic arm is the most recent addition in a series of instrumentation upgrades at the Structural Materials Beamline (SMB). One year since the robot arm’s installation, a third-party vendor visited CHESS to perform initial commissioning and safety system integration during the 2022 summer down, as planned. With these critical tasks out of the way, Drs. Kelly Nygren and Peter Ko, staff scientists at SMB, along with their collaborators, can finally start designing new state-of-the-art experiments, which otherwise would not be possible without the robotic arm.
Crystal structure of a type III Rubisco in complex with its product 3-phosphoglycerate
Recent research performed at CHESS gives insight into intermediate stages of Rubisco’s catalysis mechanism.
Protein family shows how life adapted to oxygen
Cornell scientists have created an evolutionary model that connects organisms living in today’s oxygen-rich atmosphere to a time, billions of years ago, when Earth’s atmosphere had little oxygen.
Nanocrystals with metastable high-pressure phases under ambient conditions
This groundbreaking work was supported by a collaboration between the PI an collaborators and CHEXS scientist Zhongwu Wang, spanning many years, across the former CHESS “B-line” beamline and the new CHEXS HPBio facilities. This work was enabled by custom diamond anvil cells with large opening angles for simultaneous SAXS / WAXS measurements, and by in-situ spectroscopy techniques deployed at CHESS
CHESS Welcomes New Staff Scientist - Steve Meisburger
Steve Meisburger joins CHESS as a staff Scientist at the FlexX beam line. Steve comes from the Ando Lab at Cornell, which studies how enzymes work by using a combination of biophysical and biochemical techniques. We are thrilled to have Steve join the CHESS team!
