Characteristic X-rays. Characteristic x-rays are produced by the primary electron beam displacement of an electron in the valence shell of the specimen. As the electron is displaced, an electron from a higher valence shell must fill its orbit. The result is a small amount of energy loss in the form of an x-ray photon.
