Conduct double-slit experiment

[Aditya3003]

Dr.Young's double slit experiment.

I am a 14 yr old teenager who is fascinated by Physics.I want to conduct the double slit experiment, I will require your help.

1)I want to conduct the experiment using electrons.(the one by Clauss Jonsson in 1961)

2)Will it be possible to use the electron guns of the old TFT monitors?

3)I am planning to show the experiment in a Science fair, So Can I show them the working or just the results?

4)The Experiment will be conducted in vacuum so What will be the vacuum container?Would glass work(Will light interfere with the electrons?)

5)Please add as much as details as possible as I have no help.The more the specific the better.

6)Your help will be appreciated & the helper will be listed as a special contributor in my experiment.

Thanks for your time

Gratitude.

FIrstly, I didn't think TFT monitors had anything resembling an electron gun in them, perhaps you meant CRT?

If that is the case, the electronics involved are quite high voltage and could be a bit dangerous.

Perhaps you would be satisfied by doing the experiment with a laser?

I also think you mean crt rather than tft (thin film transistor)

 

A CRT is evacuated, so you would have to break vacuum to place a target inside and then reseal and pump it out again. Furthermore, the deBroglie wavelength is going to be small — the whole reasoning behind electron microscopy — so an actual double-slit experiment requires fabrication of the target. Usually such experiments use a crystal of some sort and you are doing the equivalent of multiple-slit interference.
