Bending a Beam to Significantly Reduce Wakefields of Short Bunches
arXiv:1108.4625
Abstract
A method of significantly reducing wakefields generated at collimators is proposed, in which the path of a beam is slightly bent before collimation. This is applicable for short bunches and can reduce the wakefields by a factor of around 7 for present day free electron lasers and future colliders.
