Nonlinear Resonant Collimation for Future Linear Colliders
Abstract
We present a scheme for collimating large amplitude particles in the
main linacs of a linear collider, by adding octupoles to the FODO
lattice of the linac. The requirements on downstream collimation can
in this way be greatly reduced or perhaps even eliminated. An analytic
estimate of the amplitude at which particles are lost is made by
calculating the separatrix of the fourth order resonance, and is in
good agreement with the results of simulations. Simulations of
particle distributions in the beam core and halo are presented, as well
as alignment tolerances for the octupoles.
