Equipment required to to the electron double slit experiment ?

Click For Summary

Discussion Overview

The discussion revolves around the equipment required to conduct the electron double slit experiment, exploring the feasibility and resources needed for individuals interested in replicating this experiment, particularly in a home setting.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about resources or papers for constructing the equipment needed for the electron double slit experiment.
  • Another participant notes that a source of coherent electrons is typically expensive and may be inaccessible for most amateur experimenters.
  • A different participant claims that the double slit experiment is easy and cheap to perform at home, but acknowledges that the electron version is more complex than the photon version.
  • This participant offers a link to a blog post and later provides a corrected link to a resource related to the electron double slit experiment.

Areas of Agreement / Disagreement

There is no consensus on the accessibility of conducting the electron double slit experiment, with some participants suggesting it is feasible while others highlight significant challenges and costs involved.

Contextual Notes

The discussion does not resolve the practical limitations of conducting the experiment, such as the specific requirements for coherent electron sources and the associated costs.

Hi can any point me to a site/paper on how to construct the equipment required for the electron double slit experiment ?

Thanks

You need a source of coherent electrons, which is generally quite expensive and—assuming this is something you want to attempt yourself—out of reach for all but very rich amateurs.
 
Thanks for coming back, yar expect it might have been,
but was also interested in how it was done in detail.

Lucky you that I read this thread. The DSE is quite easy and cheap to do at home; I've tried it myself - check out my PF blog post about it here: https://www.physicsforums.com/blog.php?b=4096 . EDIT: sorry, did not notice that it was the electron version that was asked for :smile:. That's definitely not as easy to do as with photons, but I have some link about it, I'll post it when I've found it...

EDIT: Here it is (or rather, was): http://www.hitachi.com/rd/research/em/doubleslit.html, sadly the link seems to be broken :frown:.
EDIT: Here's the correct link :smile:: http://www.hitachi.com/rd/portal/research/em/doubleslit.html
