Researchers at CHESS are working to further improve the already impressive CHESS Compact Undulator, or CCU.
Within the new NSF-funded CHEXS award, Sasha Temnykh is developing a new driving mechanisms that will add variable gap control and even better tuning of the device, both desirable qualities for a variety of experimental needs.
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, making CHESS an even more powerful X-ray source.
Researchers at CHESS lead by Sasha Temnykh are working continuously to improve the already impressive CHESS Compact Undulator, or CCU. The CCUs are about ten times more compact, lighter, and less expensive compared to conventional insertion devices typically used at other lightsource. They also require a significant shorter fabrication time. Nine CCUs have already been constructed in industry from the Cornell-held patent, and according to KYMA, the manufacturer of the CCU, other labs are starting to show interest in the device.
