TECH - First light from the first high-energy superconducting undulator

(Phys.org)-More than eight years of effort by Advanced Photon Source (APS) physicists, engineers, and technicians culminated on Jan. 21, 2013, with the production of the first X-rays from the prototype of a novel superconducting undulator (SCU), which has been installed in the APS electron accelerator and storage ring at the U.S. Department of Energy's (DOE) Argonne National Laboratory. It is the first such SCU operated at a third-generation synchrotron X-ray facility.
