“…Since electrons are so sensitive to electromagnetic field, transient electric or magnetic field can deviate electron's trajectory, introducing artifacts into diffraction patterns. [7][8][9] Besides, space-charge effect (the repulsive force among electrons within each electron bunch) tends to broaden its longitudinal duration. For example, an electron bunch containing only few thousand 100 keV electrons broadens from several tenth fs at birth to more than one picosecond (ps) only after propagating about half meter long.…”

“…Another issue for TR-RHEED is the transient charging induced by pump that can deflect the electron probe. [7][8][9] Such effect must be carefully suppressed by choosing proper pump fluence and photon wavelength, or eliminated from signal by theoretical modeling. Turning disadvantage into opportunities, ultrafast electrons have been used to monitor the transient electric field distribution of various materials beyond TR-RHEED application.…”

Ultrafast electron diffraction (UED) technique has proven to be an innovative tool for providing new insights in lattice dynamics with unprecedented temporal and spatial sensitivities. In this article, we give a brief introduction of this technique using the proposed UED station in the Synergetic Extreme Condition User Facility (SECUF) as a prototype. We briefly discussed UED's functionality, working principle, design consideration, and main components. We also briefly reviewed several pioneer works with UED to study structure-function correlations in several research areas. With these efforts, we endeavor to raise the awareness of this tool among those researchers, who may not yet have realized the emerging opportunities offered by this technique.
