dynatron
electronics
Quick Summary
A dynatron is a type of vacuum tube that utilizes the secondary emission of electrons from its plate. This unique characteristic leads to a decrease in plate current as the plate voltage increases, a phenomenon known as negative resistance.1
This effect is particularly useful in oscillator circuits. While the dynatron itself is a specialized form, the principles behind its operation are related to other vacuum tubes like the tetrode, which also features a screen grid that can influence electron flow and amplify signals.2
