Abstract

A device for measuring total electron yields in the energy range 4–65 keV from conductor was set up successfully, which was made up of electron gun system, vacuum system and electrical system. By the pulse electron gun method, the total electron yields in the energy range 4–65 keV from silver were measured, based on the relation between the secondary electron yield and total electron yield at high incident electron energy from metals, the secondary electron yields in the energy range 10–65 keV from silver were deduced. Total electron yields measured with the device were compared with theoretical values, and the deduced secondary electron yield were compared with several authors' values, the results were discussed and a conclusion was drawn that the deduced secondary electron yields and the total electron yields from silver measured with the device are credible.
