AB  - In Darmstadt, Germany, the Facility for Antiproton and Ion Research   (FAIR) is presently under construction. One of the most complex machines   is the SIS100, a synchrotron with a circumference of 1100 metres. Since   the accelerating structures for heavy ions are normal conducting and   have to be operated at room temperature a cryogenic by-pass line is   required to by-pass these warm components.   The by-pass line provides continuity around the synchrotron for liquid   helium and houses the superconducting bus bars for the electric current.   This 300m long by-pass line system has been developed in close   collaboration between GSI and the Wroclaw University of Science and   Technology (WUST). The design must fulfil both the mechanical   requirements of the overall system in respect of interfaces to other   components and the demanding requirements for the arrangement of the bus   bars.   The magnet system of SIS100 will be a fast-ramped from a few hundred   amperes to almost 14 kA within 0.5 seconds. The bus bars must therefore   be both stable against electromagnetic forces and flexible to compensate   for thermal shrinkage. Following an intensiv design phase, the   production responsibilities were assigned to Kriosystem. After the   production of the first prototype, the complete series of 27 diverse   by-pass line modules, consisting of 5 main layout, was finalised.   This article summarises some of the challenges during design and   production phase, tests which were successfully carried out and, last   but not least, the installation in the tunnel. Furthermore, an outlook   is given on the upcoming final assembly and connection to the magnets.
