Electron multiplier fabrication
Fabrication and assembly details are given for the construction of a sixteen-stage silver-magnesium dynode electron multiplier. The unit has been used primarily for positive-ion detection in mass spectroscopy.
Frederick L. Reynolds, University of California, Berkeley. Radiation Laboratory, 1955

Mass Spectrometry: Principles and Applications
The discrete dynode electron multiplier is made up of a series of 12 to 20
dynodes that have good secondary emission properties. As shown in Figure 3.2,
these dynodes are held at decreasing negative potentials by a chain of resistors.

Introduction to Spectroscopy
draws the electrons further into the electron multiplier, where each electron
strikes the surface again, each causing the ejection of two more electrons. This
process continues until the end of the electron multiplier is reached, and the
electrical ...

Understanding Mass Spectra: A Basic Approach
Electron Multiplier An electron multiplier detector restores this lost sensitivity by
exploiting the ability of surfaces that contain glass doped with about 10–20%
lead oxide to expel more than one electron when a charged particle collides with
it.

Inorganic Mass Spectrometry: Principles and Applications
Such a dual ion beam collector is applied, for example, for precise and accurate
measurements of isotope ratios, especially of gases in commercial stable isotope
ratio mass spectrometers.2 4.2 Secondary Electron Multiplier For a further ...
ELECTRON MULTIPLIER steps up weak impulses to practical working power.
The signal entering at left is tripled in power at each zigzag down the metal "
ladder" in tube. Increasing fluorescence in ladder demonstrates power increase.

Applications of LC-MS in Toxicology
The most common detection device is the electron multiplier. In an electron
multiplier, ions are converted into electrons by means of a dynode electrode -
when an ion strikes the dynode surface (made of secondary emitting materials,
e.g. CsSb ...
This system is useful mainly when working with a surface ionization source and
an electron multiplier ion detector, where instabilities in the ion source are
pronounced and where drifts in the gain of the multiplier are expected. It is not
practical ...
