The reduction of transient stored beam perturbations generated by top-up injection into storage rings has since long been a topic of intense research and development in the synchrotron radiation community. The issue is particularly relevant to present and future fourth-generation storage rings, for which beam stability is a crucial performance parameter. In this paper, we report on the design and commissioning of a novel multipole injection kicker (MIK) that has successfully demonstrated high injection efficiency as well as outstanding transparency, with levels of residual disturbances to the stored beam well below the beam size in both the horizontal and vertical planes.

长期以来，减少由加注到存储环中而产生的瞬态存储束扰动一直是同步加速器辐射界的研究重点。这个问题与现在和将来的第四代存储环特别相关，因为光束稳定性是关键的性能参数。在本文中，我们报告了一种新型多极注入喷射器（MIK）的设计和调试，该产品已成功证明了高注入效率以及出色的透明性，并且在两种情况下，对存储光束的残留干扰水平均远低于光束尺寸。水平和垂直平面。
