Description
Summary:The article describes the electron beam scanning system in combination with electromagnetic focusing system. These systems find their application in different vacuum tube devices that provide the generation of X-ray radiation. Similar systems can be utilized in such fields as medicine, industry and defectoscopy. Electron tube system can be based on thermal or field emission cathodes. Scanning system is built up on two pair of electrical deflecting dipoles. The scanning can also be based on magnetic deflecting system. Beam focusing is achieved by the geometrical features of electrodes structure and electron lenses. Magnetic focusing can also be used for transversal focusing of the beam. The article describes the schemes of the unit with electron beam scanning and different methods of realization. Beam dynamics investigation in electromagnetic fields of the unit is considered.
