在2018年夏季和秋季，康奈尔高能同步加速器光源（CHESS）正在进行升级，以增加X射线用户的高能通量。升级需要更换康奈尔电子存储环（CESR）的六分之一，反转一半CHESS束线的极性，并切换到单束同轴操作。新的六分仪是由六个双弯消色差（DBA）与组合功能偶极四极。虽然DBA设计被广泛使用和理解，但CESR修改的约束使CHESS-U晶格独特。本文介绍了设计目标，约束条件，并实施CESR加速器升级CHESS-U。
During the summer and fall of 2018 the Cornell High Energy Synchrotron Source (CHESS) is undergoing an upgrade to increase high-energy flux for x-ray users. The upgrade requires replacing one-sixth of the Cornell Electron Storage Ring (CESR), inverting the polarity of half of the CHESS beam lines, and switching to single-beam on-axis operation. The new sextant is comprised of six double-bend achromats (DBAs) with combined-function dipole-quadrupoles. Although the DBA design is widely utilized and well understood, the constraints for the CESR modifications make the CHESS-U lattice unique. This paper describes the design objectives, constraints, and implementation for the CESR accelerator upgrade for CHESS-U.
