Cryostat Design for the Bent Superconducting Dipole Magnets and Cryogenic Layout for the HESR at FAIR

The Forschungszentrum Juelich (FZJ) has taken the leadership of a consortium to design and construct the HESR as part of the Facility for Antiproton an Ion Research (FAIR) project at the Gesellschaft fuer Schwerionenforschung (GSI) in Germany. The HESR is a 50 Tm synchrotron/storage ring for antiprotons using superconducting magnet technology, where the development of a bent dipole magnet (cosine theta) with a radius of curvature of 13.9 m and a length of 3.3 m is the major task.
