X-ray tube - Wikipedia

An X-ray tube is a vacuum tube that converts electrical input power into X-rays. The availability of this controllable source of X-rays created the field of radiography, the imaging of partly opaque objects with penetrating radiation.In contrast to other sources of ionizing radiation, X-rays are only produced as long as the X-ray tube is energized.
