Abstract

The anode 30 of an X-ray tube comprises an X-ray emissive target insert 88 of tungsten for example embedded in the surface of an anode block 52 of copper for example, the interface 122 between the insert 88 and the block 52 being concave towards the external emission surface of the insert 88. In order to prevent thermally induced stresses causing the insert to separate from the block, the interface 122 is contoured to lie on an isothermal surface and the insert 88 may thus be substantially semi-ellipsoisal. Shear stresses at the interface are thus eliminated. Cooling channels 70, 74 in the anode block can be distributed to tend to establish an isothermal surface at the interface 122.
