Abstract :
In order to preserve the very small beam emittance in the main linacs of future high-energy linear colliders, a new alignment method, the so-called ballistic alignment method, has been developed. A description of the method is given and it is applied to the Compact Linear Collider (CLIC). In this scheme the quadrupoles are divided into bins which are corrected one after the other. In the first step, the quadrupoles in a bin are switched off to use a ballistic beam to align the beam position monitors (BPMs). Next, a simple one-to-one correction is used to align the quadrupoles. The dependence of the emittance growth on different error sources is investigated
