SUMMARY

The measuring device traditionally used to observe electrons passing through slits is a photographic plate, which contains silver metal salts (Ag+) that convert to colloidal silver upon exposure to electrons or photons. Additionally, a simple pick-up loop, essentially a loop of wire, can also serve as a measuring device by generating an induced current when electrons pass through it. This induced current can be amplified using a pre-amplifier (pre-amp) for better signal detection. Both methods provide effective means to observe electron behavior in experiments.

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.
