    Notes: A control system has been developed for the 1.8 T wiggler to be delivered to the Synchrotron Radiation Research Center in Hsinchu, Taiwan. The system serves three major functions: gap monitoring and control, end-corrector adjustment and tracking, and interlock safety and monitoring. The end correctors are programmed with a gap-following feature for compensation of the electron trajectory in both transverse planes at all gaps. Software and hardware interlocks are provided for overtravel limits and protection against excessive variation in gap from end to end. The system is designed for stand-alone operation as well as for compatibility with the SRRC central control system. Because the wiggler controller is based on a personal computer and uses the LabVIEW programming language, it is readily adaptable for other wiggler or undulator applications. © 1995 American Institute of Physics.

    Development of a 1.8 T permanent magnet wiggler system (abstract) : Proceedings of the 5th international conference on synchrotron radiation instrumentation (1995)

    Notes: The design, development, and realization of a 1.8 T permanent magnet hybrid wiggler system is presented. This 3.0 m wiggler has a 200 mm period, operating at a minimum gap of 22 mm. It has 27 poles and integrated end correctors and field clamps. The magnetic design for this device is pushed to a regime where few hybrid devices have operated. The very large peak field causes a significant increase in the saturation of the vanadium permendur poles. The operating point also significantly impacts the transverse uniformity of the field and the magnet operating point. The magnetic design approach and the development of a mechanical structure which provides adequate strength and stability are discussed. The system is a complete stand-alone system with a fully integrated controls system and complete insertion device magnetics measurement system. The adjustment of the end compensation of the device with the presence of the field clamps requires particular attention. The distinctive elements of the design and the result of the magnetic and mechanical testing of the device are presented. This wiggler is being delivered to the Synchrotron Radiation Research Center for installation at the beginning of 1995. © 1995 American Institute of Physics.
