    • The application concerns a target backing tube for a rotatable cylindrical target assembly (120) comprising : a tube (122a) for at least one target element (126a) to be disposed there around, wherein the tube has an exterior surface adapted to face the at least one target element, wherein a portion of the exterior surface of the tube has a mean emissivity of 0.7 to 1, wherein the portion is at least 50% of the exterior surface of the tube. Further, the application concerns a cooling shield for a sputtering system comprising a rotatable target, the cooling shield has an interior surface adapted to face a target element of a sputtering system and an exterior surface; wherein a portion of the interior surface of the cooling shield has a mean emissivity of 0.7 to 1, wherein the portion is at least 50% of the interior surface of the cooling shield. Additionally, the application concerns a target element for a rotatable cylindrical target assembly of a sputtering system, wherein the target element an interior surface adapted to face a target backing tube onto which the target cylinder is adapted to be disposed and exterior surface, wherein a portion of the interior surface of the target element has a emissivity of 0.7 to 1, wherein the portion is at least 50% of the interior surface of the target element.
