rotating anode. focal track made of tungsten -rhenium which spins on the copper anode rotor and has molybdenum backing because these metals conducts it draws the heat away from the anode. - because the anode is rotating the electrons dont hit at the same spot everytime so the anode does not over heat. focal spot.
The copper anodes are placed into a solution of copper sulfate and sulfuric acid. The copper then migrates across the solution to the cathode, also made of copper to maintain purity. The reactions are: Copper cathode is 99.97% copper in sheets of dimensions: 96 cm x 95 cm x 1 cm, with a mass of about 100 kg.
