  This lecture gives an introduction into the design of high-energy storage
ring lattices. Applying the formalism that has been established in transverse
beam optics, the basic principles of the development of a magnet lattice are
explained and the characteristics of the resulting magnet structure are
discussed. The periodic assembly of a storage ring cell with its boundary
conditions concerning stability and scaling of the beam optics parameters is
addressed as well as special lattice insertions such asdrifts, mini beta
sections, dispersion suppressors, etc. In addition to the exact calculations
that are indispensable for a rigorous treatment of the matter, scaling rules
are shown and simple rules of thumb are included that enable the lattice
designer to do the first estimates and get the basic numbers 'on the back of an
envelope'.
