Franck-Hertz experiment with a Ne-tube

Project Description

Principle

Electrons are accelerated in a tube filled with neon vapour. The excitation energy of neon is determined from the distance between the equidistant minima of the electron current in a variable opposing electric field.

Tasks

  1. To record the counter current strength I in a Franck-Hertz tube as a function of the anode voltage U.
  2. To determine the excitation energy E from the positions of the current strength minima or maxima by difference formation.
