An optimized superferric wiggler design for the International Linear Collider damping rings.

摘要

Experimental and simulation-based analyses of the superferric wigglers operating in the Cornell Electron Storage Ring (CESR) have provided significant practical experience with a wiggler-dominated accelerator. A modified version of the CESR wiggler will be discussed and shown to meet all physics performance specifications for the International Linear Collider (ILC) damping rings. Results from optimizations of the parameters of this wiggler will also be discussed and shown to both maintain the physics performance and additionally provide modifications that reduce the wiggler's cost and engineering risk. The design and simulated performance of the superferric ILC-optimized CESR-c (SIOC) wiggler will be presented, leading to a recommendation of the SIOC wiggler as the baseline ILC damping wiggler.
