IEC FRANCK HERTZ EXPERIMENT SET
The IEC 'Franck Hertz' experiment board consists of an electron valve configured as a miniature laboratory to detect the behaviour of Xenon gas atoms when bombarded with electrons. It is self-contained with an electron tube, a Thyratron, that contains Xenon gas in the glass envelope and various electrodes to permit the excitation of the gas molecules.

Power supplies are required for the tube heater and the anode/cathode voltage. The system is complete with an inbuilt 9V battery and amplifier so the very small currents can be seen on ordinary bench meters if a sensitive mirror galvanometer is not available.

The manual gives a clear explanation of how the Thyratron works, energy levels and the theory behind the experiments. Detailed instructions are included for experiments in the:
• First Excitation Potential of Xenon gas
• Ionisation Potential of Xenon gas

Socket Terminals:
• HEATER - Power source for the heater (typ. 6.3V AC)
• 12V/24V DC SUPPLY G1-K - Power source for the Grid (typ. 0-24V DC)
• 100V DC SUPPLY - Power source for the Anode (typ. 0-100V DC)
• DC VOLTMETER G1-K - Connection for a voltmeter to measure voltage set between cathode and control grid.
• µA GALVANOMETER - Connection for a sensitive galvanometer to measure very small currents (1-2 µamps)
flowing in the anode circuit. These terminals are used ONLY when the inbuilt DC Amplifier is switched OFF.
• mA METER - Connection for a normal student milliammeter or multimeter if a sensitive Galvanometer is not available.
These terminals are active ONLY when the inbuilt DC Amplifier is switched ON.
• METER AMPLIFIER - Switch to operate the optional inbuilt DC Amplifier. When selected the correct connections are automatically made for the Anode circuit and no connections are required at the Anode terminals.
A red LED indicates that the Amplifier is switched ON.

A suitable 100V power supply is LB2621-001.
