The electrons are accelerated by repulsion from the cathode
and attraction to the anode. In class we are told that the final electron
beam velocity is a function of the difference between the Cathode and the
Anode voltages. Why aren't the electrons simply reattracted to the anode
upon passing. So that the net accel is due only to the Cathode voltage?
