摘要

脉冲多极磁铁注入方法是近年来储存环上新兴的一种束流注入方案，具有注入元件少和对储存束流扰动小等优点。本文研究了在合肥光源(Hefei Light Source

HLS)上储存环采用单块脉冲八极磁铁实现束流注入的设计方案。通过物理过程推导和计算，在储存环上选择合适的八极磁铁的安装位置，初步确定相应的磁铁参数。对注入过程进行跟踪模拟，结果验证了注入束流的存活效率较高，对于储存束流的扰动比脉冲四极磁铁和脉冲六极磁铁注入方法更小，证明了在HLS上采用单块脉冲八极磁铁完成注入过程是可行的。

Abstract

Background: In recent years

a new injection system with pulsed multipoles magnet is developed

which consists of a single magnet and gives little distortion to the stored beam. Purpose: The paper demonstrated the injection scheme using a single pulsed octupole magnet (POM) at the Hefei Light Source (HLS) storage ring. Methods: The location and the parameters of the POM are determined by the physics calculation and numerical simulation of injection process by simulating and tracking. Results: Compared with injection using pulsed quadrupole or sextupole magnet

the distortion to the stored beam is much smaller than that with a single octupole magnet. And the injection acceptance is about 4 mm×0.2 mrad while the capture efficiency exceeds 97%. Nonetheless 3-turn injection becomes the main factor which limits the acceptance of injection. Conclusion: Using the POM injection system

the quality of synchrotron light is more stable

resulting in more working time for scientists. Generally we demonstrated the feasibility using the POM injection at the HLS storage ring. Abstract
