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.…
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…
