Fast Optimization Techniques Applied to Linear and Non-Linear Lattices of Electron Storage Rings and Accelerators

This paper describes a general interactive computer program, ZEN, developed to determine linear focussing parameters for CESR, the Cornell electron storage ring, and application of similar methods to non-linear elements. It is particularly suitable for lattices of electron accelerators, especially those with large numbers of independently variable focussing parameters. ZEN is a descendent of the linear lattice calculating program, MAGIC, Ref. 1, having improved interactive capability and new minimization routine, MINOP Ref. 2.
