you have been asked to design a magnet system to steer a beam of 54eV. The goal is to direct the electron beam to a spasific target with an accuracy +,- 1mm. In the design, do you need to take the wave nature of electron into account? EXPLAIN...

Solution

Wave nature of the electrons need to be considered in order to design a system that direct the electron beam to the specified target. The electrons are scattered by the planes of atoms at the surface of the crystal. Atoms are arranged in rows in the surface plane with distance d, which acts as the reflecting diffraction grating used to measured the diffraction techniques. The electron beam is consider as the wave in this context.

By varying the applied voltage the electron wavelength is determined which effects the sharpness and the resolution of the image formed.

Thus the electron beam needs to be considered as the wave to design the magnet system to direct the electrons in the specified direction.
