In the original form of this analytical technique, a device consisting of a glass tube with a resistive coating uses an electric field to accelerate incoming electrons into collisions with the wall, such that more electrons are ionized and hence a detectable current pulse is formed on the detector.
In the original form of this analytical technique, a device consisting of a glass tube with a resistive coating uses an electric field to accelerate incoming electrons into collisions with the wall, such that more electrons are ionized and hence a detectable current pulse is formed on the detector. This device is called a channeltron. In more conventional forms, hemispherical electron energy analyzers are used to measure the kinetic energy of incoming electrons. Pioneered by Siegbahn in 1954 for which he received the Nobel prize in 1981, this analytical technique measures kinetic energies and the intensity of electrons escaping from the first 1-10 micrometers of a surface. In this method electron binding energies are calculated by subtracting the measured electron kinetic energies and known work functions from energies of photons generally obtained from synchrotron sources. FTP, name this ubiquitous technique which is based on an effect discovered by Einstein in 1905.
