Fast dynamic aperture optimization with reversal integration
Yongjun Li, Yue Hao, Kilean Hwang +3
A fast method for dynamic aperture (DA) optimization of storage rings has been developed through the use of reversal integration. While chaotic dynamical systems have exact time-re…
Bayesian Approach for Linear Optics Correction
Yongjun Li, Robert Rainer, Weixing Cheng
With a Bayesian approach, the linear optics correction algorithm for storage rings is revisited. Starting from the Bayes' theorem, a complete linear optics model is simplified as "…
Analysis of beam position monitor requirements with Bayesian Gaussian regression
Yongjun Li, Yue Hao, Weixing Cheng +1
With a Bayesian Gaussian regression approach, a systematic method for analyzing a storage ring's beam position monitor (BPM) system requirements has been developed. The ultimate pe…
Reconstruction of Storage Ring 's Linear Optics with Bayesian Inference
Yue Hao, Yongjun Li, Michael Balcewicz +2
A novel approach of accurately reconstructing storage ring's linear optics from turn-by-turn (TbT) data containing measurement error is introduced. This approach adopts a Bayesian…
Characterization and control of linear coupling using turn-by-turn beam position monitor data in storage rings
Yongjun Li, Lingyun Yang, Weixing Cheng
We introduce a new application of measuring symplectic generators to characterize and control the linear betatron coupling in storage rings. From synchronized and consecutive BPM (…
Optimize Nonlinear Beam Dynamical System with Square Matrix Method
Yongjun Li, Li Hua Yu, Lingyun Yang
Nonlinear dynamics has an important role when designing modern synchrotron lattices. In this letter, we introduce a new method of using a square matrix to analyze periodic nonlinea…
