实施了一种用于超级KEKB电子高能环（HER）的同步加速器注入方案，并在束流碰撞期间进行了顶补注入的首次尝试和实验评估。HER注入点的晶格配置为提供-1.6米的大水平色散，注入束流能量相应设置为比环能量高+0.6%。由于束流引出系统位于注入点附近，光学设计受到限制以确保与其要求兼容。利用环内逐圈束位置监测器（TbT-BPMs）建立了注入参数的系统调谐程序，成功消除了注入束流的 betatron 振幅。使用优化的环光学，成功演示了向HER的同步加速器注入，随后建立了稳定碰撞并产生了光度。
英文摘要
A synchrotron injection scheme for the SuperKEKB electron high-energy ring (HER) was implemented and experimentally evaluated as the first attempt with a top-up injection during beam collisions. The lattice at the HER injection point was configured to provide a large horizontal dispersion of -1.6 m, and the injection beam energy was accordingly set to +0.6% above the ring energy. Since the beam extraction system is located near the injection point, the optics design was constrained to ensure compatibility with its requirements. A systematic tuning procedure of the injection parameters has been established with turn-by-turn BPMs(TbT-BPMs) in the ring, by which the betatron amplitude of the injected beam was successfully removed. Using optimized ring optics, synchrotron injection into the HER was successfully demonstrated, followed by the establishment of stable collisions and the production of luminosity.
