Another geometry of continuous-dynode electron multiplier is called the microchannel plate.
2.
Photomultipliers with large distances between the photocathode and the first dynode are especially sensitive to magnetic fields.
3.
The continuous dynode was resistive, and its ends were connected to enough voltage to create repeated cascades of electrons.
4.
Each subsequent dynode impact releases further electrons, and so there is a current amplifying effect at each dynode stage.

6.
Because these electrodes are separate from each other, this might be called a " discrete-dynode " multiplier.
7.
This group of primary electrons is electrostatically accelerated and focused by an electrical potential so that they strike the first dynode of the tube.
8.
Once it exits the electron gun, its inertia makes the beam move away from the dynode towards the back side of the target.
9.
The impact of a single electron on the dynode releases a number of secondary electrons which are in turn accelerated to strike the second dynode.
