Abstract:
To provide Landau damping there must be particles in the beam whose incoherent tune coincides with the tune of coherent oscillations which is close to the bare lattice tune. The incoherent tunes, however, are shifted by space charge forces by as much as -0.06 for the present beam parameters and by -0.09 for the PIP-II parameters. Here we study the possibility of using octupoles to provide a comparable tuneshift without destroying the dynamic aperture.
