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.

摘要：北京正负电子对撞机重大改造工程(BEPCⅡ)采用的是新型冲击磁铁Slotted Pipe kicker,其结构上要求双极性供电．平衡变压器是实现双极性的关键部件,是解决脉冲源闸流管阴极可直接接地的绝好技术途径．平衡变压器是一种具有特殊用途的高压快脉冲变压器,因此其设计除了要解决高压快脉冲变压器的一般性技术问题外,还必须着重考虑电流平衡度指标．通过理论分析、模拟计算和测试实验证明不平衡电流主要由变压器的励磁电流和磁芯涡流损耗等效电流两部分组成．平衡变压器磁芯材料和几何尺寸选取,以及原副边导体结构设计是实现设计指标的关键所在．样机测试结果与设计计算结果相符,验证了平衡变压器设计理论的正确性,且平衡度D＜1%达到预定指标．
