An electron gun is not an elaborate piece of equipment. I empowered you to verify it for yourself. Have your physics PhD son perform it, he will tell you it is trivial to do (if he is competent at all).
Now since you are completely full of it, exhibit nothing but an obstinate oppositional-defiance reflex, have no genuine curiosity whatsoever about the subject, and have nothing positive to contribute to any part of this discussion, take a hike.

Since your proposal defies all written science why would I set about another experiment that would only prove you wrong.
