Characterization of a 6-km Damping Ring for the International Linear Collider

Several damping ring designs for the International Linear Collider (ILC) have been proposed recently [1]. One particular design has a circumference of ∼ 6 km (hoping to take advantage of future kicker technology advances) using TME arc cells and 77 m of 2 T wigglers. In this paper, we report beam dynamics characterizations and optimizations for this design. We used the accelerator code elegant [2] for matching and tracking and a 100-CPU Linux cluster to provide high throughput.
