An X-ray source is a vacuum tube that produces X-rays, also called an X-ray tube. To generate X-rays, a current is first passed through the filament to heat it. The filament generates hot electrons, which are accelerated by high voltage and collide with the target of the anode.

The energy of the X-rays is proportional to the tube current of the X-ray tube and to the square of the tube voltage. Less than 1% of the thermal electrons become X-rays, most of which are heat.

X-ray sources can be classified into two types: closed tube and open tube. The sealed tube type is further classified into fixed anode type and rotating anode type. They are also classified into anode grounded type, cathode grounded type, and bipolar type according to the connection method of the power supply.

X-ray sources are used in medical x-ray and CT equipment, industrial non-destructive analysis equipment, and X-ray analysis equipment (XRF, XRD). In the field of non-destructive testing, there are also X-ray tubes called microfocus X-ray tubes for finer inspection.
