Main linac emittance growth and luminosity in future linear colliders

Wakefield and dispersive effects in the main linac of a future linear collider can strongly affect the beam-beam interaction at the collision point. For a static situation, this paper investigates the luminosity for realistic bunches in the case of the TESLA, NLC and CLIC projects assuming different degrees of collision optimisation. A part of this work was performed for the International Linear Collider Technical Review Committee.
