Observing Electrons: The Measuring Device & Its Name

[Hussein Tofaili]

What is the measuring device used to observe electrons while passing through the slits? Has it a name?

I think that traditionally there was a photographic plate behind the slits and the pattern of the electron waves developed on it. A black and white photography plate contains silver metal salts, which have $Ag^+$ ions in them and they can be converted to pitch black colloidal silver metal when exposed to electrons or photons.

This doesn't require anything sophisticated. A pick-up loop (i.e. basically a loop of wire) is sufficient, because an electron passing through a conducting loop generates an induced current in the loop. One just need to feed the signal to a pre-amp to amplify the signal.
