The superconducting 7 Tesla wiggler is destined for the Center for Advanced 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 wiggler will be installed in the CAMD site in December of 1997. The wiggler 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 inserted into a special liquid helium cryostat. The main distinction of this 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 compensation is realized by two conventional correcting magnet located at the both ends of the wiggler straight section. Characteristics of the magnetic system, helium cryostat and radiation properties of the wiggler are described in this article.
