Type-II superconductors, like the Nb_{3}Sn used in the new HL–LHC quadrupole triplet and 11 T dipoles or FCC dipoles, are known to show an unstable behavior during magnetic-field ramps. This paper presents an analysis of the possible effects on the beam dynamics of this behavior of the magnets, with a focus on emittance blow-up.
