Simulation study on the optimal shape of electrodes quadrupole electrostatic deflectors for the UTEM

In this paper, the electrostatic field of a quadrupole electrostatic deflector used in ultrafast transmission electron microscopy is simulated. When the electrodes of the deflector are arcs and straight plates with different degrees of curvature, there is a significant difference in the distribution...
