Now can we get back to discussing stuff more intelligent than this.
not just yet , theres still a problem.
electrons are not light , only photons are light.
since the path of a photon can be curved by a magnet
as evidenced in the green laser video
then my thoughts on this is that as the electrons of the
atoms in the gas molecules become excited by photons
or electrons and then emit a photon , the emitted photons
are following the same curve that the electrons follow
resulting in a directed chain of excitation of the
electrons of atoms followed by the re-emission of photons
that follow the same electrically induced path .
this would maintain the focused beam of light that you do
see and would not result in a diffusion of light caused by undirected or unfocused light.
I think that you are thinking more about a chain of
random non directed non focused events causing the
light beam that we see.
the only basic difference between a old style residential incandesant light bulb and a electron gun is that the electron gun focuses the particles that exit the apparatus and the
old style light bulb doesn't.
focus is very important in lasers and crt tubes and electron guns .. without focus theres nothing but diffusion of particles whether they are photons or electrons.
