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…
A simple approach for power density calculation of spontaneous radiation emission from a finite emittance electron beam in planar undulators
Ganesh Tiwari, Timur Shaftan
We extend the angular power density formulae for spontaneous radiation emission from planar undulators to include finite emittance and angular misalignment of the electron beam. Th…
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.…
Electron beam emittance at operational intensity in fourth-generation synchrotron light sources
Victor Smaluk, Timur Shaftan
For synchrotron light sources, the brightness of user X-ray beams is primarily determined by the electron beam emittance and energy spread at operational intensity. A common featur…
Optimize electron beam energy toward in-situ imaging of large thick bio-samples with nanometer resolution
Xi Yang, Victor Smaluk, Timur Shaftan
To optimize electron energy toward in-situ imaging large bio-samples up to 10-um thickness with nanoscale resolution, we implemented an analytical model based on elastic and inelas…
Towards construction of a novel nm resolution MeV-STEM for imaging of thick biological samples
X. Yang, L. Wang, J. Maxson +11
Driven by life-science applications, mega-electron-volt Scanning Transmission Electron Microscope (MeV-STEM) has been proposed to image thick biological samples. The high penetrati…
