Include additional grids to improve efficiency and reduce signal distortion.
Examples include "magic eye" tubes for signal display, thyratrons, and magnetrons. Key Technical Details vacuum tube
Placed between cathode and anode to control the volume of electrons. Include additional grids to improve efficiency and reduce
Basic rectifiers, converting AC to DC.
Positively charged electrode that attracts the electrons. vacuum tube
Heated (white-hot) to "boil off" electrons via thermionic emission.
Introduced the grid for amplification.
