TUPMF022	Electron Beam Scanning in the Delta-Type Undulators for Sirius	1300
	A. B. da Cruz, L. Liu LNLS, Campinas, Brazil
	We report on simulation studies to analyze the possibility of scanning the electron beam, and not scanning the sample, in CDI experiments using a Delta-Type undulator in the 3GeV Sirius electron storage ring presently under construction at LNLS. This would allow much faster scans in diffraction limited storage rings such as Sirius. We study displaced beam trajectories through the undulators and analyze the effects on the emitted radiation. It is possible to show that displacements on the order of ± 500 micrometers around the center will introduce variations in the radiation spectrum that are less that 1 per cent and thus acceptable for Coherent Diffraction Imaging experiments.

Sirius is a Synchrotron Light Source Facility based on a 4th generation 3 GeV low emittance electron storage ring that is under construction in Campinas, Brazil. Presently the main tunnel for the accelerators is ready to start installations. The Linac tunnel was delivered earlier and the 150 MeV Linac from SINAP is almost ready to start commissioning early May. Commissioning of the storage ring is expected to start by the end of this year (2018). In this paper we briefly review the overall project parameters and design concepts and focus on highlights from the main subsystems.
