就在不久前，第三代储物戒指的技术，还被认为是成熟的。大多数第三代储存环使用双弯消色差透镜（DBA）或三弯消色差透镜（TBA）概念。然而，众所周知的事实是，增加环中的磁单元的数量是降低电子束发射度并因此降低源亮度的有效方法，但代价是增加环的尺寸和成本。当增加磁单元的数量时，保持环中的动态孔径（DA）也成为一个问题。多弯曲消色差透镜（MBA）概念，包括环元件的小型化，现在已经彻底改变了这一局面。MBA戒指，现在正在建设或正在规划中，提供数量级更高的亮度比传统设计的戒指。世界各地的一些光源现在正在实施或计划实施这一MBA概念。本文涉及更高的辉煌的科学驱动力。然后我们将描述...
Not very long ago, the 3rd generation storage ring technology was judged as mature. Most of the 3rd generation storage rings used the Double-Bend Achromat (DBA) or Triple-Bend Achromat (TBA) concepts. It was however a well-known fact that increasing the number of magnet cells in the rings is a powerful way of decreasing the electron beam emittance and thus the source brilliance, but at the penalty of increasing the size and cost of the rings. Preserving the Dynamic Aperture (DA) in the rings became also an issue when increasing the number of magnet cells.The Multi-Bend Achromat (MBA) concept, including a miniaturization of the ring elements, has now drastically changed the picture. The MBA rings, now in construction or being planned, offer orders of magnitudes higher brilliance than rings of conventional designs. Several light sources around the world are now implementing or planning to implement this MBA concept.This article touches on the science drivers for higher brilliance. We will then describe the ...
