Kilo Electron Volts, keV
unit used to measure the energy of X-rays emitted from atoms when excited by the electron beam of an SEM.
Discussion—By definition, one electron volt is the amount of energy gained (or lost) by the charge of a single electron moving across an electric potential difference of 1 V. One kilo electron volt is 1000 eV.
