nice observation, I will keep it in mind I think I have an interesting project in mind

you mentioned that the proposed methods differ in their efficiency, I wanted to know if there is any paper that reports on the efficiency of the method of positively charging the anode to reduce the power consumed

is there any documentation or paper about that?

but we can add a passive focusing for the beam, I would love to do a simulation about it

thanks for your response! ok, let's forget about VDGG for a moment and go back to the electron gun. What happens if previously before accelerating the electrons we first positively charge the anode by some known method (friction, conduction or induction) so that the anode acquires a high...

I had a hard time understanding how the consumption of hundreds of watts using an accelerator voltage source can be replaced by a simple 12v x 0.5A dc motor running a van der graaf generator Thanks a lot again!

Ok but there is no power consumption to accelerate the electron beam?

Thanks a lot! one more question: What happens if instead of a high voltage source we put a positively charged metal plate as anode The electron beam will be accelerated but there is no power consumption ? (assuming that the beam is perfectly focused and no electron will hits the anode) Who...

The power consumption due to accelerating the electron beam, I am not assuming that the electrons will hit a target, I am only interested in the power consumption of acceleration part

First Assume the following basic circuit: I read in many textbooks that the electrons in the circuit are accelerated by the positive voltage and decelerated by the collisions, so the speed is constant. We also know that the circuit current is I = 10A so the power consumed is P = V * I = 100W...
