Wake field suppression in high gradient linacs for lepton linear colliders

beams in a linear collider must be adequately damped in order to preserve the luminosity of the colliding beams and to prevent a beam breakup instability developing. A review of the means of achieving this wakefield suppression is discussed in detail for normal conducting linacs utilized for linear colliders. In particular, the features of a damped and detuned series of structures are described and compared to other methods. A conspectus of experimental results along with theoretical predictions for this series of accelerating structures developed for the next-linear-collider/global-linear-collider is presented together with the prospects for wakefield suppression for the compact linear collider.
