To Twin or Not to Twin: Micromechanical Response in Magnesium probed with High Energy X-Rays
Reducing the weight of vehicles translates into energy conservation in transportation which is beneficial for economic and environmental reasons.
Lead uptake and distribution in horns from goats
Spatial analysis of horns for lead accumulation may be useful as a qualitative marker of time-resolved exposures that may reflect specific periods of acute lead absorption.
A Brilliant Relationship - Detector Development at Cornell
Detectors are critical to any synchrotron lightsource, they help characterize the samples being probed, as well as the X-rays that interrogate them. Certain detectors can tell researchers about the intensity, energy, position and timing of X-rays; all crucial information needed to commission and tailor experiments for users. The detector’s main purpose for the users of CHESS, however, is to produce detailed imagery, revealing hidden traits in samples such a
Beyond the Lab with Elisabeth Bodnaruk
Elisabeth Bodnaruk seems very comfortable as she looks into the container of liquid nitrogen. At -321 degrees F, liquid nitrogen is widely used throughout CHESS, but right now she is using it to commission some Resistance Temperature Detectors (RTDs). These RTDs will be placed in two silicon crystal monochromators where they will transmit temperature readings, and are an integral part of daily operations in the lab.
Nearest neighbors and beyond: Reciprocal space imaging of ionic correlations in intercalation compounds
The ability to generate a real-space ‘image’ of interatomic vectors from reciprocal space data, makes this technique a powerful tool in the investigation of intercalation compounds.
Step-by-Step: Revealing the mechanism of a protein-cleaving enzyme by crystallographic snapshots
These unusual enzymes have been implicated in diseases ranging from Alzheimer’s disease to malaria, type II diabetes, cancer, Parkinson’s disease, cholera and tuberculosis.

CHESS Hosts Workshop on Advanced Manufacturing of Engineering Alloys
A major impediment to the adoption of new advanced manufacturing processes of engineering alloys (including additive manufacturing) in industrial settings is the high prevalence of defects in finished products which can negatively influence performance.
Welcome Back Users!
Louise Debefve stands outside a hutch on the experimental floor of the Cornell High Energy Synchrotron Source, CHESS. She is preparing the experimental equipment for some of the first data to be collected at CHESS since the completion of the CHESS-U upgrade.
A Winning CHESS Opening
The upgrade, which was funded by New York State and completed in early 2019, involved reconfiguring and optimizing the Cornell Electron Storage Ring for the production of X-rays and the concurrent refurbishment of the X-ray experimental areas to exploit the redesign of the storage ring.
The driving force behind Cornell Compact Undulators at CHESS
Undulators are critical devices for the creation of brilliant X-rays at CHESS and other lightsources around the world. With the recent CHESS-U upgrade, the Cornell Electron Storage Ring, CESR, is now outfitted with seven new insertion devices. As the beam circulates around CESR, it passes through a series of alternating magnets in the undulators, resulting in X-rays that are roughly 20 times brighter than those produced prior to the upgrade, maki
