Outline • Beam dynamics with synchrotron radiation: • Define action-angle variables for describing symplectic motion of a particle along a beam line. • Discuss the effect of synchrotron radiation on the (linear) motion of particles in storage rings. • Derive expressions for the damping times of the vertical, horizontal and longitudinal emittances. • Introduce the synchrotron radiation integrals (Sand’s Integrals). • Discuss the effects of quantum excitation, and derive expressions for the equilibrium horizontal and longitudinal beam emittances in an electron storage ring. • M.
