Production of x-ray

The production of X-rays occurs when electrons are accelerated under a potential difference and turned into electromagnetic radiation. An X-ray tube, with its respective components placed in a vacuum, and a generator, make up the basic production of x-ray components.

Two types of x-ray production occurs.

There are 2 types of x-ray production. they are

A) Bremsstrahlung radiation.

B) Characteristics radiation.

A) Bremsstrahlung radiation :-  When the high speed electrons are passes by the nucleus , it is decelerated resulting in loss of kinetic energy of electrons and the loss of kinetic energy Is converted into x-ray is called Bremsstrahlung x-ray.

When the electrons are pass near the nucleus. The nucleus has positive charged and electrons has negative charged. The negative charged attracted at the positive charged. The electron is attached towards the nucleus and thus deflected from their original direction. The electron loss their energy and slow down when it’s direction changes. The kinetic energy lost by the electron is emitted directly in the form of photons of radiation. The x-ray produced by this process is called Bremsstrahlung radiation or general radiation.

B) Characteristics radiation :- When the high moving electron bombarding the target eject electrons from the inner orbits of the nucleus. The ejection of inner she’ll of the the orbit leaving an ionised atom with unfilled inner shell. That time the electrons from the outer orbit fill the vacant of inner shell orbit. This types of transection is called characteristic radiation.

The binding energy of an electron in the K shell of tungsten is 70 keV and the cathode electron have more energy of 70 keV to eject the K shell electron from the inner shell.
