A 6-T SUPERCONDUCTING WIGGLER FOR SYNCHROTRON-RADIATION

A three pole superconducting wiggler magnet has been constructed to be : used as a light source in a 1.5 GeV electron storage ring at the Uni versity of Lund, Sweden. The main design principles have been reported in [1] and [2], With a central flux density B-0 of 6 T, the high fiel d wiggler will produce X-rays with a critical wavelength of 1.38 Angst rom. During construction three different kind of racetrack type windin gs were made. The comparison concerning the magnet stability between t he different coil concepts has been evaluated with different supportin g structures and magnet ramping rates. The main performance of the mag net system and the influence of training are discussed, Quench analysi s and the cryogenic facility are also included in the discussion.
