X-Ray Diffraction (XRD) systems analyze the structure of materials such as crystals and powders. The X-Ray Tube generates heat from the interaction of electrons in the cathode and the anode. The electrons emitted from the cathode (filament) are accelerated towards the anode – when the electrons hit the anode, they produce x-rays. Keep in mind that the focal “spot” on the anode is most commonly only 12×0.4mm rectangular. The full power of the generator is being dissipated
