| Abstract | We present a s c heme 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 begreatly 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 goodagreement with the results of simulations. Simulations of particle distributions in the beam core and halo are presnted, as well as alignment tolerances for the octupoles. Abstract. We present a s c heme for collimating large amplitude particles in the main linacs of a linear collider, by adding octupoles to the FODO lattice of the linac. With this scheme the requirements on downstream collimation can be greatly reduced or perhaps even eliminated.
