WebX-rays can also be produced by a synchrotron. A synchrotron is a device that accelerates electrons in an evacuated ring (often several tens of metres in diameter), steering them with magnets. Manipulating the electron beam in a controlled way with the magnets can produce intense beams of X-rays. The mechanisms for producing x-rays from free electrons are similar to those responsible for production of other energies of electromagnetic radiation. The motion of a free electron (for example, one that is unbound to an atom) may produce X-rays if the electron is undergoing any one of these motions: See more This mechanism operates in all X-ray sources. It originates from theacceleration of electrons in coulomb collisions with other electrons … See more Synchrotron radiation is associated with the acceleration thathappens to electrons as they spiral around a magnetic field.
