Franck - Hertz Tube
For demonstrating the discontinuous release of energy by free electrons upon collision with mercury atoms, and for determining their excitation energy. The Franck-Hertz curve is plotted either point-by-point with indicating instruments or continuously by means of a recorder or CASSY.
Vacuum tube with indirectly heated cathode, emission control grid, anode grid, collector and a mercury drop which vaporizes when the tube is heated.
Please note: the Franck-Hertz tube (555 854) can only be used in conjunction with the corresponding sockets (555 864/555 865). It is not possible to run it on the socket for the old Franck-Hertz tube (555 85, no longer available).
Technical Data:
- Filament: 3.15 V/0.4 A
- Grid voltages:
Emission grid: 0 - 4 V DC
Anode grid 0 - 40 V DC - Counter-voltage at collector: approx. 1.5 V DC
- Socket: 8-pin socket
- Mercury filling approx. 5 g
- Excitation energy of the Hg atoms 4.9 eV
- Operating temperature: approx. 200 °C
- Dimensions: 10 cm x 2.8 cm diam.
