The alignment results of the tandem EPU at Taiwan Photon Source

Abstract

Abstract Since its inauguration for user applications in 2016, the Taiwan Photon Source (TPS) has facilitated numerous research endeavors. The current investigation focuses on the alignment results of a tandem Elliptically Polarizing Undulator (EPU) situated within an extended double minimum beta y long straight section. The objective is to augment the photon flux of the synchrotron light generated by the tandem EPU via accurate alignment and using a phase shifter to attain temporal coherence. A cross-correlation function is employed to scrutinize the beam parameters associated with the source points to evaluate the temporal coherence of the two light sources emitted from the tandem EPU.
