Abstract :
Wiggler insertions are expected to occupy a significant portion of the lattice of the Next Linear Collider (NLC) main damping rings (MDR) and have a noticeable impact on the single-particle beam dynamics. Starting from a realistic 3D representation of the magnetic fields we calculate the transfer maps for the wigglers, accounting for linear and nonlinear effects, and we study the beam dynamics with particular attention paid to the dynamic aperture (DA). A DA reduction is observed but appears to remain within acceptable limits.
