WebApr 11, 2024 · Gregory J. Gbur— Invisibility—the ability to make something invisible to visible light—has long been assumed by science to be impossible.This changed in 2006, when two groups of researchers published back-to-back papers in the journal Nature demonstrating theoretically that invisibility is, at the very least, plausible. Since then, there has been … 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. The forcefelt by a charged particle in a magnetic field is perpendicular to thedirection of the … See more This process does not generate new photons, but scatters photons fromlower to higher energies (or vice versa) in interactions with electronsof higher (or lower) energies.
