1. An anode for an x-ray tube comprising:
- a disk of a dense anode material which has been formed by explosively compressing an anode form with a shaped explosive charge, the shape of the charge being selected to compress the anode form uniformly at least in a target area of the anode form.

Abstract
An explosive forming process provides an anode (10) suitable for use in a high energy x-ray tube. The process includes applying a shaped charge (54, 80, 90, 92) to a refractory material which has been formed in the general shape of the anode. The configuration of the charge is calculated to provide a target area (16) on the anode of uniform, high density which does not tend to outgas in the high vacuum conditions of the x-ray tube. The explosive process is capable of forming anodes with much larger diameters than is possible with conventional forging techniques.
