Generation of X-rays

Laboratory X-ray sources can be classified into two types: sealed-tube and rotating anode. Both may be used to generate monochromatic X-ray radiation and they basically differ only in the intensity of the radiation produced.

White Radiation

X-rays are generated when matter is irradiated by a beam of high-energy charged particles such as electrons. In the laboratory, a filament is heated to produce electrons which are then accelerated in vacuum by a high electric field in the range 20-60 kV towards a metal target, which being positive is called the anode. The corresponding electric current is in the range 5-100 mA. The process is extremely inef...
