So, i am doing this experiment where i have a hot filament which is shooting a beam of electrons. Beam is accelerated by two plates with a constant potential. I have a vacuum pump to pump out air and decrease the pressure in the container (cylindrical chamber). I want to derive a formula where i...

This makes sense but i am just confused how i should correlate pressure directly with the maximum penetration distance of electron beam. I tried using deceleration, momentums and other techniques

I am actually interested in a beam of electron

Hey! I am trying to figure out this one problem. Some help would be appreciated. How can i relate the maximum distance traveled by an electron at a given pressure? So electron is colliding with air molecules. I wonder if there is a formula or derivation which relate maximum penetration and...
