anode

the positive electrode or pole to which negative ions are attracted.
The stationary anode in an x-ray tube is a solid bar of copper with an inset of tungsten on the face of the bar opposite the cathode filament. The tungsten target has a high melting point to withstand the intense heat of the x-ray beam—the copper conducts the heat away.

anode-film distance
see focal-film distance.
rotating anode
an x-ray tube in which the anode rotates when x-rays are being produced. This means that there is a larger effective target surface of the anode which can be available to generate x-rays.
stationary anode
a non-rotating anode in an x-ray tube so that the target surface is comparatively small.
