The measurement of the higher levels of 6/sup 3/P/sub 2/ and 6/sup 1/P/sub 1/ of the mercury atom in the Franck--Hertz experiment has been introduced into the junior and senior laboratory course by using a homemade tetrode Franck--Hertz tube. The main structure of the tube is described. The optimum operating conditions are in the temperature range between 130 and 150 /sup 0/C and the collector currents are of the order of 10/sup -9/ A. The additional observations of the famous Franck--Hertz experiment in the laboratory course will give the students more familiarity with the quantum behavior of atoms.
