Abstract :
It is pointed out that future linear colliders with extremely low emittance beams seems to require strong BNS damping in order to cope with wakefield effects. Under this condition the smooth focusing approximation is overoptimistic as compared to AG focusing. For the CERN Linear Collider (CLIC) it is found that the emittance blow-up due to wakefields in a nonperfect machine is about one order to magnitude smaller for smooth than for AG focusing
