This experiment tries to demonstrate that electrons can travel a short distance through air and can penetrate a thin aluminium window known as a Lenard Window, after the discovery by Philipp Lenard. Originally a fluorescent screen was used to show the beam. I am using a Geiger counter assuming the electrons can be detected as Beta radiation.
