Description	Journal: Journal of Physics E: Scientific Instruments A high-energy electron gun (5-50 keV), used in an electron-atom collision apparatus, has been equipped with a special generator to supply the Wehnelt voltage. A feedback device acts on this voltage and allows one to keep constant (to better than $10^{-3}$) either the intensity of the electron beam, or the intensity scattered by the target.
