Abstract :
To generate hard X-ray beams for residual stress analysis and for magnetic scattering using the BESSY II ring, a 7T wiggler with 17 poles is under development. The wiggler is designed for a critical energy of 16.8 keV with a 13 mm vertical free aperture and an inner chamber on a temperature of 20 K. Essential aspects of the conceptual magnet layout are discussed, e.g. coil and yoke geometry, and vacuum chamber design. A prototype structure with 7 poles has already been built to verify the technical layout of the wiggler. First experimental results for the prototype magnet are presented, demonstrating that a maximum field of 7.3 T can be obtained with the present design
