                         On 9th May we advised that "Due to Trump's tariffs all Vernier prices are going up by 10% as new stock arrives so buy NOW".  With the lower tariffs announced on the 12th May we can advise that all Vernier prices are only going up by 5% as new stock arrives.  Gosh I hope there are no more changes of undies!!       Due to foreign exchange and freight costs many Molymod products will or have already increased in price.

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.
