Description
As a core component of the Hefei Advanced Light Facility (HALF), the storage ring's magnetic element arrangement accuracy and beam optical performance directly affect the device's operating efficiency and beam quality. To address potential geometric deviations during the installation of the HALF storage ring, this paper focuses on smooth adjustment, establishing an analytical framework from two aspects: geometric adjustment and verification of physical and optical indicators.
By conducting constraint analysis on the positions of key magnetic components and the connection deviations of adjacent sections, it was determined whether the adjustment scheme satisfies the physical threshold conditions required for HALF storage ring operation. Secondly, based on beam dynamics, indicators such as β function, dispersion function, and closed-orbit distortion are selected to further verify the state of the geometrically adjusted storage ring and evaluate its impact on beam stability and optical matching.
Through these two levels of verification, the rationality of the smoothing adjustment scheme for the HALF storage ring can be comprehensively assessed. This study provides a reference for HALF storage ring alignment optimization and subsequent operation and commissioning.
