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.

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.  

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
