Evaluation of the component tolerances for the ILC Main Linac assuming global linear corrections

The small energy-spread, weak wakefields and relatively weak focusing in the international linear collider (ILC) superconducting Main Linac result in little or no filamentation beam mismatch errors: linear correlations such as dispersion or cross-plane coupling from transverse misalignment or rotation errors of the quadrupoles respectively do not decohere as the beam is transported (accelerated) along the linac. Using corrections available in the Beam Delivery System (BDS), the increase in projected emittance due to this linear correlations can to a large degree be corrected. In this paper we present component tolerances based on the assumption of a global correction at the end of the Main Linac. Some discussion on the impact of ground motion is also given.
