Experiment: Thermionic Diode (230 V, 50/60 Hz)

Experiment: Thermionic Diode (230 V, 50/60 Hz), 8000656 [UE3070100-230], Experiments with Electron Tubes
Thematic focus: ..
•  Record the characteristic for a thermionic diode at different cathode heater voltage
•  Identify the space charge and saturation regions
•  Confirm the Schottky-Langmuir law

In a thermionic diode, free electrons carry a flow of current between the heated cathode and the anode when a positive voltage is applied between the cathode and anode. The current increases along with the voltage until a saturation point is reached. However, if the voltage is negative, the current is zero.
