Design and optimization of the NSLS-II lattice with complex bend replacement
Minghao Song, Yoshiteru Hidaka, Bernard Kosciuk +4
The demand for brighter photon beams has driven the development of diffraction-limited storage rings with ultralow electron beam emittance. A complex bend (CB) lattice was recently…

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…

Online regularization of Poincaré map of storage rings with Shannon entropy
Yongjun Li, Kelly Anderson, Derong Xu +7
Shannon entropy, as a chaos indicator, is used for online Poincaré map regularization and dynamic aperture optimization in the National Synchrotron Light Source-II (NSLS-II) ring.…
