Super-FRS is a new in-flight fragment separator that is currently being installed at the Facility for Antiproton and Ion Research (FAIR). It will produce exotic isotopes for nuclear physics experiment from intense heavy-ion beams accelerated by the SIS100 synchrotron. The topic of this thesis will be to simulate the impact of these intense beams as well as secondary fragment beams on superconducting multiplets, an assembly of several superconducting magnets housed within a single cryostat. The goal is to evaluate the risk of quenches and determine intensity limits which will be implemented into the machine protection system of Super-FRS.
