When a short (mm-length) bunch with high (nC-regime) charge is transported through a magnetic bending system, self-interaction via coherent synchrotron radiation and space charge may cause emittance growth. Earlier the authors studied analytically the shielded transient self-interaction of a rigid-line bunch entering from a straight path to a circular orbit, and estimated the concomitant emittance degradation in parts of Jefferson Lab`s infrared free-electron laser (IR-FEL). In this paper, they generalize their earlier results by calculating the curvature-induced steady-state longitudinal wakefield on particles with transverse offsets from the design orbit. Recent progress in developing a self-consistent simulation are also presented.
