Is it possible to measure the displacement of a single electron in an electric field? If so, how far down can we resolve the distance down to; mm, um, nm, pm?
For example if a electron travels perpendicular through an electric field at a uniform velocity, similar to a cathode ray tube. Would we track the electrons position by using a vision system (would a vision system be a sufficient way of detecting an electron) and filling the tube full of helium?
Now say if the electric field increased by 1ppm causing a tiny displacement in the electrons path would a vision system be able to resolve this tiny displacement?
Also does anyone have any ideas of producing and trapping a single electron or a mono energetic "ball of electrons? Does electron levitation actually exist? How do they currently detect the presence of an electron?
Sorry about the amount of questions I am just really interested to know.
I thank you in advance
