Photomultiplier |
---|
Electrons produced following collision of an ion with a conversion dynode strike a phosphorous screen to produce a burst of photons. Cascade amplification of these photons, in a manner similar to electron amplification within an electron multiplier results in an increased signal that is converted into a measurable current. Photomultiplier are sealed units that prevent contamination and hence increase the lifetime of the unit. |
