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

What did the scientists discover?

The group took an extensive tour of CHESS and met with many members of the technical, engineering scientific and administrative staff, all integral to the success of the upgrade of the facility.  After the tour, while enjoying coffee and donuts in Wilson Lab Commons with CHESS and CLASSE staff, Linda Sapochack expressed how impressed the NSF team was with the new facility, the progress made to date, and the professionalism, commitm
