An electrode used in certain electron tubes to provide secondary emission.

[Greek dunamis, power; see dynamic + -ode.]


(General Physics) an electrode onto which a beam of electrons can fall, causing the emission of a greater number of electrons by secondary emission. They are used in photomultipliers to amplify the signal

The application EPC technology by using zinc oxide (ZnO) nanoparticles immobilized on zinc (Zn) sheet-copper electrode, and lamp emitting dynode (LED) ultraviolet-A (UV-A) lamp for the treatment of pathogenic strains of Pseudomonas aeruginosa were reported (Kashi, 2015).
The 6470 features an ion detector with a high-energy conversion dynode and low nose characteristics, promoting more efficient positive and negative ion detection and mass range; and powerful MassHunter data handling software, including triggered MRM, which helps increase analytical confidence.
The detector consists of an assembly formed by a thallium-activated sodium iodide crystal (NaI(Tl) 2"x2") connected to a photomultiplier, a light guide, a voltage divider, a resistor divider, a dynode, and a preamplifier.

With all the homework and car adjustments that the E&B Crew Chief Brownie Brown did, the car ran numbers 18% higher than the dynode session.
Ion detection was by secondary electron multiplier, the ions hit a conversion dynode and the electrons produced were amplified in an electron multiplier which can operate in either counting or analog mode.
