Spectrum analyzers release process

After separation of the ions produced, a detector, usually a continuous dynode version of an electron multiplier, is used to count the ions and generate a mass spectrum. Such a detector is shown schematically in Figure 10.8. Ions from the mass analyzer strike the semi-conductive surface and release a cascade of electrons. These are accelerated by a potential difference to another portion of the semi-conductive surface where a larger cascade of electrons results. This process is repeated several times until amplification of the original weak input is magged about 1-million-foId.
