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.
