Typical dimension of an apparatus for electron interference

[universal_101]

Greetings

This is my first post in this section of PF.

As the title says, I just want to know the typical dimensions of the two-slit experiment, intended for electron interference. That is, what are the slits made of, what is their spacing from the screen,source and from each other.

Is there any other form of physical slits that is not based on the thin wire separation of the slits, like electron bi-prism.

And what is the typical uncertainty of the energy of the bombarded electrons.

Any other information that you think I skipped mentioning would be welcomed.

Thanks for your time.

Thank you for your question regarding the dimensions of the two-slit experiment for electron interference. The typical setup for this experiment involves two narrow slits, usually made of a thin material such as metal or glass, with a spacing of a few micrometers between them. The distance from the slits to the screen and source can vary, but is typically in the range of a few centimeters to a few meters.

There are other forms of physical slits that can be used for this experiment, such as an electron bi-prism, which uses a thin wire to create the two slits. This can produce similar interference patterns as the traditional two-slit setup.

The uncertainty of the energy of the bombarded electrons can vary depending on the specific setup and conditions of the experiment. However, in general, the energy uncertainty can range from a few electron volts to a few kilo electron volts.

It is also important to note that the dimensions and conditions of the two-slit experiment can greatly affect the resulting interference pattern, so it is important to carefully control and measure these parameters in order to accurately analyze the results.

I hope this information helps answer your questions. If you have any further inquiries, please do not hesitate to ask.
