Abstract

Two consistent sets of parameters for damping rings which lack wigglers and comply with the required performance for the CLIC (CERN Linear Collider) have been worked out. They both have small circumferences (200 to 300 m) and are operating at low energy (e=2 to 3 GeV). They are based on two new, specially developed cells: a compact lattice optimized for small equilibrium emittance, and a cell equipped with reverse bending magnets to improve damping. This is a combination of a wiggler lattice and a compact cell recently proposed for small emittance and large dynamic acceptance. The very small dispersion function all along the cell makes negligible the blow-up induced by intrabeam scattering
