TUA2C05	Introduction to the Session on Lattice Optimization for Stochastic Cooling	lattice, pick-up, kicker, betatron	96
	D. Möhl CERN, Geneva
	Lattices that circumvent the ‘mixing dilemma’ for stochastic cooling have repeatedly been considered but were not adopted in the original design of existing cooling rings. Recently new interest has arisen to modify existing machines and to design future ‘optimum mixing rings’. This talk is meant to summarize the pros and cons with the aim to introduce the discussion.

TUA2C07	Advanced HESR Lattice with Non-Similar Arcs for Improved Stochastic Cooling	lattice, pick-up, kicker, dynamic-aperture	102
	Y. Senichev FZJ, Jülich
	Optimized stochastic cooling requires special ion optical conditions in a storage ring. The frequency slip factor strongly influences the mixing factor, and strong requirements have to be fulfilled by the unwanted mixing of the path from pickup to kicker and the wanted mixing on the way from kicker to pickup. Several ideas for a lattice with "irregular" momentum compaction factor have been investigated. The influence of possible lattice modifications to the stochastic cooling performance for COSY will be discussed. Investigations of a lattice optimized for the stochastic cooling in HESR will be summarized.
