In summary, the conversation discusses the possibility of measuring the displacement of a single electron in an electric field and the limitations in terms of how small of a distance can be resolved. It also explores the use of a vision system, which is a camera and computer software, to track the position of the electron and detect its presence. The conversation also delves into the idea of producing and trapping a single electron and the existence of electron levitation.

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

Jon

What is a "vision system"?

Basically using a camera and computer to visually analyze the electron activity. Sfotware would be installed on the computer with brightness detection threshold limits. So when a photon is given out, from the interaction of the electron with helium, the camera would capture this and the software would process the signal from the camera. The software would have a statement which says when the brightness levels reach a certain value this means that an electron is present.
