Emittance growth in the collider arcs due to transverse wakefields

The three main components of the dipole wakefield in the collider arcs are the resistive wall wake due to the finite conductivity of the vacuum chamber wall and the wakes due to discontinuities at the beam position monitors and vacuum chamber bellows. In the first section we estimate the dipole wakefield arising from the resistive wall wake. In the second section results of TBCI calculations of the wakes due to the BPM's and bellows are presented, and compared with the resistive wall calculation. In the final section the total wakefield is used to compute the emittance growth
