ALS-U的升级承诺在整个软X射线范围内提供有限的衍射性能，将水平发射度降低到约50 pm，从而使软X射线的亮度比目前的ALS提高2-3个数量级。该设计采用了具有同轴换出注入的多弯消色差晶格和一个累加环。一个主要的设计目标是在短时间内安装和调试ALS-U。本文总结了加速器概念设计的现状，以及近3年来进行的研究开发计划的一些结果。
The ALS-U upgrade promises to deliver diffraction limited performance throughout the soft x-ray range by lowering the horizontal emittance to about 50 pm resulting in 2-3 orders of brightness increase for soft x-rays compared to the current ALS. The design utilizes a multi bend achromat lattice with on-axis swap-out injection and an accumulator ring. One central design goal is to install and commission ALS-U within a short dark period. This paper summarizes the status of the conceptual design of the accelerator, as well as some results of the R&D program that has been ongoing for the last 3 years.
