Development of a magnet system for the CERN BDF/SHiP Facility

The SHiP experimental setup requires a magnet-based shield immediately after the proton target in order to deflect the very large background flux of muons away from the detector acceptance. To this end, a magnet system integrated within the hadron stopper in the target bunker has been proposed. The aim of this work was to move the design of the magnet system within the target shielding from a conceptual stage to a preliminary engineering design. This was done taking into account the strict constraints on the design and integration aspects of the magnet system imposed by the integration and remote handling of the target complex. In order to arrive at a sufficient level of understanding of the implementation of the magnet system, its performance and costs, and the development timeline, STFC completed a preliminary engineering design in close collaboration with the BDF target complex team and the SHiP experiment team.
