DAFNE升级的动态孔径优化

Dynamic Aperture Optimization for the DAFNE Upgrade

Eugene Levichev, Pavel Piminov, Pantaleo Raimondi, Mikhail Zobov

摘要:

最近提出的新想法的“蟹腰”光束光束碰撞将在DAFNE在运行的Siddharta实验的对撞机进行测试。为了达到目标亮度,大动态孔径是首要问题。提出了一种基于分步色度补偿的动态孔径优化新方法,在每一步中选择“最佳”的六极子对。考虑到高光度和大动态孔径,考虑了几个调谐点。最后给出了优化的算法和结果。

英文摘要:

Recently proposed novel idea of "crabbed waist" beam-beam collisions will be tested at DAFNE during the collider run for the Siddharta experiment. In order to achieve the goal luminosity, large dynamic aperture is a matter of primary importance. A new method of a dynamic aperture optimization based on step-by-step chromaticity compensation with choosing the "best" sextupole pair at each step was applied to the DAFNE upgrade lattice. Several tune points were considered taking into account both high luminosity and large dynamic aperture. Algorithm and results of optimization will be presented.
