dynode in Science
An electrode used in certain electron tubes, especially photomultipliers, to provide secondary emission. Dynodes are arranged by increasing voltage between the cathode and anode of the tube, each attracting the cascade of electrons from the one behind it, and releasing more electrons to the next.
