Abstract
A magnetic deflection system for a high-power electron beam with an expanding cross-section area is used for melting or vaporizing metallic materials. Saddle coils are provided which open in a direction of expansion of the electron beam. With the aid of these saddle coils large deflection speeds of the electron beam are obtained with small imaging errors and large deflection angles.
