It all depends on the strength of the electrical field gradient that is causing them to move, Electrons flowing in a conductor move at a speed of a few meters per second but when they move in an CRT they move close to the speed of light.

Even more so. An electron can be accelerated in frame X and then maintain that velocity in that frame. The one can change their frame of reference to one which is moving parallel to x an with a faster speed. In that new frame the velocity is moving faster in that new frame.

I find your post rather puzzling do you have a cyclotron in mind ?.
