Conceptual design of Hefei Advanced Light Source(HALS)injection system

摘要

The Hefei Advanced Light Source(HALS)is a super low emittance storage ring and has a very short beam life time.In order to run the ring stablely,top-up injection will be necessary.The injection system will greatly affect the quality of beam.This article first gives a physics design of the injecting system.Then the injecting system is tracked under different errors.The responses of storage beam and injecting beam are given in the article.
