FIELD: electricity.
SUBSTANCE: multi-section collector of electric vacuum device with recuperation is suggested, made in the form of hollow cone. Hollow cone is made monolithic from aluminium nitride by method of hot-pressing, metal closed conductors are made by means of laser beam scanning of external surface of hollow cone in points of their corresponding installation at the depth that is equal to hollow cone thickness. At that thickness of hollow cone and width of metal closed conductors are determined by output parameters of electric vacuum device.
EFFECT: increase of output power and efficiency factor; increase of reliability, durability and manufacturability.
