Experiment Topics:_..

The following topics can be discussed with this Neon-filled, partial-vacuum electron tube:
• Discharge, evidence of positive charge carriers
• The I_A – U_Acharacteristic of a thyratron
• Non-self-sustaining discharge
• Self-sustaining discharge
• Simplified Franck-Hertz-set-up

Product Information:_..

The gas triode is a Neon-filled tube with a pure tungsten heater filament (cathode) and a round metal plate (anode) with a wire grid between them, all inside a clear glass bulb. The cathode, anode and grid are all aligned parallel to one another. This planar configuration corresponds to the conventional symbol for a triode. A circular metal plate attached as a backing to the filament ensures that the electric field between the anode and cathode is uniform.
The gas triode allows recording of the I_A – U_A characteristic of a thyratron, observation of excited and non-excited discharge and of the discontinuous transfer of energy by Neon atoms in inelastic collision with free electrons (simplified Franck-Hertz-set-up).
