Developments of novel insertion devices (IDs) for storage rings (SR) and free-electron lasers (FELs) have remained quite active in recent years. The next generation of synchrotron radiation facilities, such as the already constructed or proposed storage rings at MAX-Lab, LNLS, ESRF, APS and SPring-8, provide strong motivation for continued improvements in IDs design and performance. Existing and newly built FEL facilities around the world also contribute important aspects of IDs fabrication: fast production of high quantity and high quality undulators that could be promptly installed in the FEL tunnels. Research institutions along with scientifically-oriented industries develop multiple approaches for the design and fabrication of single, unique IDs as well as a large quantity of standardized devices. A wide spectrum of existing and novel IDs for storage rings and FELs permits tailoring of ID performance to sometimes very specific experimental requirements. Currently, designers of light sources as well as users-experimentalists can choose from a variety of novel IDs that include undulators with wide spectrum coverage and relatively uniform flux, devices with controlled polarization properties, and electromagnetic undulators with fast polarization switching. Many of these undulators exploit new engineering solutions for their mechanical systems that make these devices quite compact and less expensive. The progress in the development of superconducting undulators has been quite noticeable in recent years. Once their construction is industrialized, these undulators could become the devices of choice for the next generation of storage rings and FELs. |

TUPJE068 | Development and Performance of 1.1-m Long Superconducting Undulator at the Advanced Photon Source | 1794 |

Funding: Work supported by U.S. Department of Energy, Office of Science, under Contract No. DE-AC02-06CH11357. Development of superconducting undulators continues at the Advanced Photon Source (APS). The second superconducting undulator, SCU1, has been built and installed in the storage ring of the APS. This undulator has a 1.1-m long superconducting magnet and utilizes an improved version of the cryostat of the first superconducting undulator, SCU0. The results of the cold test of the SCU1, and its performance in the APS storage ring are presented in this paper. |
