PROPOSAL OF SUPERCONDUCTING 7 TESLA WIGGLER FOR LSU-CAMD

The superconducting 7 Tesla wiggler is destined for the Center for Adv anced Microstructures and Devices (CAMD), Louisiana State University ( LSU), USA. The wiggler contract was awarded to the Budker Institute of Nuclear Physics (Budker INP) in the open tender in May 1996 and the w iggler will be installed in the CAMD site in December of 1997. The wig gler is a three pole superconducting magnet with maximum field of 7 T in central pole and the side poles field of 1.65 T. The wiggler is ins erted into a special liquid helium cryostat. The main distinction of t his wiggler from others is that the horizontal orbit deviation at the maximum field of the wiggler central pole is equal to zero due to the special orbit compensation at any level of wiggler field. Such compens ation is realized by two conventional correcting magnet located at the both ends of the wiggler straight section. Characteristics of the mag netic system, helium cryostat and radiation properties of the wiggler are described in this article.
