【 摘 要 】

A direct space-charge force model has been implemented in the tracking code elegant. The user can simulate transverse space-charge effects by inserting spacecharge elements in the beamline at any desired position. Application to the International Linear Collider damping ring is presented in this paper. We simulated beam under equilibrium conditions, as well as the entire damping cycle from injection to extraction. Results show that beam halo is generated due to space-charge effects. This would be a significant concern for the ILC damping ring and a detailed follow-up study is needed.
