Photomultiplier tubes contain a chain of dynodes. (The tube in the photo to the left has ten dynodes). Each dynode in the chain is held at a potential relative to the next, and is coated with secondary emissive material.

Dynode - Wikipedia, the free encyclopedia
A dynode is one of a series of electrodes within a photomultiplier tube. Each dynode is at a more positive electrical potential than its predecessor. Secondary emission occurs at the surface of each...

We propose a new scheme for a phase-modulation fluorometer (PMF) in which a photomultiplier tube (PMT) is used as a photo detector whose gain is modulated sinusoidally with a burst signal of period T and duty ratio 0.5. ... Phase-Modulation Fluorometer Using a Dynode-Voltage Burst-Modulated Photomultiplier Tube...

Using a trifluoroacetic anhydride derivatization procedure and the High Energy Dynode detector system, we improved by 6.25-fold the limit of detection for delta-9- tetrahydrocannabinol in plasma over that obtained with the same GC/MS system without the new detector (80 vs 500 ng/L). The new detector system will thus...
