Description
The storage ring of the Hefei Advanced Light Facility has a circumference of approximately 480 m and consists of 20 hybrid six-bend achromatic (H6BA) lattice units with a natural emissivity of approximately 86 pm·rad. High-brightness diffraction-limited light sources place higher demands on alignment. This paper focuses on the HALF lattice and uses the Accelerator Toolbox (AT) utility program for high-fidelity error analysis and calibration simulation. Sensitivity assessments for different error sources are presented, and the optical degradation laws under overall beam misalignment and superposition states are investigated. The usability boundary under uncorrected conditions is also given.
