Abstract
A rotatable anode for an X-ray tube is provided including a hollow rotatable anode wheel having two circular faces. One of the circular faces has a bevelled edge for a target region. A circular baffle is situated concentrically inside the hollow anode wheel. The baffle has means for imparting a tangential velocity to a liquid. The outer perimeter of the circular baffle is spaced away from the interior of the anode wheel. Means for supplying cooling liquid to the central portion of one side of the baffle is provided as well as means for removing cooling liquid from the other side of the baffle. Structural means are provided for rotating the baffle and the anode wheel at the same angular velocity.
