A Simplified Model for Fast Optimization of Free-Electron Laser Oscillator
Kai Li, Minghao Song, Haixiao Deng
A simplified theoretical model for free-electron laser oscillator (FELO) simulation which reserves the main physics is proposed. In stead of using traditional macro particles sampl…
Bandwidth broadening of X-ray free electron laser with the natural gradient of planar undulator
Minghao Song, Jiawei Yan, Kai Li +2
Besides the target to pursue the narrow bandwidth X-ray pulses, the large bandwidth free-electron laser pulses are also strongly demanded to satisfy a wide range of scientific user…
Design study of a low emittance complex bend achromat lattice
Minghao Song, Timur Shaftan
Light sources worldwide have experienced rapid growth in the last decades, pushing towards higher brightness with lower emittance to meet growing demands from the user community. T…
Sextupole reduction via chaos suppression at the National Synchrotron Light Source II
Yongjun Li, Minghao Song, Yoshiteru Hidaka +2
We revisit the nonlinear lattice design approach for the National Synchrotron Light Source II (NSLS-II) storage ring. By suppressing chaos, we identify alternative sextupole config…
Machine learning for design optimization of storage ring nonlinear dynamics
Faya Wang, Minghao Song, Auralee Edelen +1
A novel approach to expedite design optimization of nonlinear beam dynamics in storage rings is proposed and demonstrated in this study. At each iteration, a neural network surroga…
Multi-objective multi-generation Gaussian process optimizer for design optimization
Xiaobiao Huang, Minghao Song, Zhe Zhang
We present a multi-objective evolutionary optimization algorithm that uses Gaussian process (GP) regression-based models to select trial solutions in a multi-generation iterative p…
