![]() ![]() Nonetheless, these sources suffer from a few shortcomings such as incoherent radiation and low-efficiency in radiation generation. synchrotron-like, X-ray radiation on a laboratory scale. Highly relativistic electrons with Lorentz factors 1 scatter photons into a narrow cone centered on their propagation direction with an opening angle of 2/. Inverse Compton scattering (ICS) sources are one of the promising compact tools to generate short wavelength radiation from electron beams based on the relativistic Doppler effect. Inverse Compton scattering generates low-divergence partially coherent quasi-monochromatic, i.e. The absorption of multiple photons of the electromagnetic field by the charged particle causes the consequent emission of an X-ray or a gamma ray with energy comparable or higher with respect to the charged particle rest energy. The polarization of inverse Compton emission usually arises from averaging the results from elemental scattering processes over a range of electron energies and propagation directions. Non-linear inverse Compton scattering is a scattering process belonging to the category of light-matter interaction phenomena. Furthermore, differently from Compton scattering, this process is explicitly non-linear because the conditions for multiphoton absorption by the charged particle are reached in the presence of a very intense electromagnetic field, for example, the one produced by high-intensity lasers. Inverse Compton scattering can create attosecond x-ray pulses by high-intensity lasers driving free electrons. ![]() This process is an inverted variant of Compton scattering since, contrary to it, the charged particle transfers its energy to the outgoing high-energy photon instead of receiving energy from an incoming high-energy photon. Non-linear inverse Compton scattering ( NICS), also known as non-linear Compton scattering and multiphoton Compton scattering, is the scattering of multiple low-energy photons, given by an intense electromagnetic field, in a high-energy photon ( X-ray or gamma ray) during the interaction with a charged particle, in many cases an electron. Electron-many photon scattering Picture of non-linear inverse Compton scattering. We scrutinize the polarization properties of inverse Compton scattered unpolarized CMB photons in Section 3.4, and study the polarization properties of inverse Compton radiation emitted in the KleinNishina regime in Section 3.5. ![]()
