abstract = {Octupole magnets are a central mitigation method against
the transverse collective instabilities expected for the
high-intensity operation of the SIS18 and SIS100
synchrotrons in the FAIR project. For these beam parameters,
the self-field space-charge effect dominates the betatron
footprint, and strongly modifies the instability drive and
the Landau damping properties. The space-charge tune shifts
are related to all three incoherent amplitudes, and is an
intrinsic interaction. We consider all these effects and
study Landau damping of head-tail modes due to the
combination of octupoles and space-charge. Using the data
from experimental instability observations, and particle
tracking simulations, we provide estimations for the
expected high-intensity operation of the SIS synchrotrons.},
