    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.

    End-field design and tuning methods for insertion devices : The 9th National conference on synchrotron radiation instrumentation (1996)

    Notes: The magnetic field distribution, gap-dependent steering, and integrated magnetic multipole moments of insertion devices installed in synchrotron radiation sources have stringent requirements for yielding high brightness without adversely perturbing the electron orbit. Correct termination of the ends of the device yields a large number of full-field poles and helps achieve gap-independent steering. End-field tuning methods used for the Advanced Photon Source insertion devices are reviewed. Techniques include magnet strength reduction, reduced height poles, magnetic shims, and pole shaping. Measurements show that two-imensional finite element analysis is a useful tool for predicting general field shape and trajectories. However, experimental entrance steering of different devices with identical end configurations shows variance, necessitating empirical fine tuning of each device. © 1996 American Institute of Physics.

    Undulator engineering for synchrotron radiation applications : International conference on synchrotron radiation instrumentation (1989)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 60 (1989), S. 1881-1884

    Notes: Six undulators have been designed and built by STI since 1980 for synchrotron and FEL applications. Several design concepts, producing successively higher fields, have been developed during this period. A wedged-pole hybrid design has been demonstrated to yield the highest field to date for a given gap-to-wavelength ratio. A simple method of reducing field errors has been demonstrated on the wedged-pole hybrid, and it may lead to significant cost reduction through relaxation of mechanical and magnet tolerances.
