Secondary electronic emission and methods of its study

In the article physical and mathematical process models of secondary electronic emission of secondary electrons, wrested from hurled when irradiating a surface of metal by the flow of primary electrons are considered. Analysis of processes, running in the efficient emitters at the condition of irradiating by scanning bunch and choice necessary hardware and technical facilities has been offered. It has been considered an inaccuracy of measurement of secondary electronic emission factor under different checking. The theoretical motivations for the building mathematical models of leaving the secondary electrons from the solid-state under the action of falling on it flow of primary electrons are considered. On mathematical models, based on the result of deciding a kinetic equation, an algorithm of calculation of true secondary electronic emission factor depending on energy of primary electrons has been designed. A structured scheme of automated software-technical complex, allowing measure a factor of secondary electronic emission of different material with the high degree of validity are stated.
