摘要
为实现BEPCⅡ的总体要求 ,对直线注入器的强流电子束和正电子束进行了系统的束流光学模拟和优化研究 .提出了束流光学的自动校正环路 .系统地研究了束流初始偏轴和加速器部件的安装误差对束流归一化发射度和轨道偏移的影响 .提出了采用“一对一”的束流轨道校正机制 ,以有效抑制这些影响 ,确保直线注入器的束流性能 .
To meet the upgrading goals of the BEPCⅡ-linac, the beam modeling and studies on optimizing the optics for high current electron and positron beams are carried out. An optics-tuning scheme is defined. The effects of initial beam axis deviation and machine alignment errors on normalized beam emittance growth and on beam orbit offset are systematically studied, and the orbit correction with '1-to-1' correction scheme is modeled.
