Compton Scattering
In the early 20th century, research into the interaction of X-rays with matter was an emerging field. It was observed that when a beam of X-rays is directed at an atom, an electron is ejected and the light is scattered through an angle θ, as illustrated below. Classical electromagnetism predicts that the wavelength of scattered rays should be equal to the initial wavelength; however, experiment...
متن کاملUltrahigh brilliance quasi-monochromatic MeV γ-rays based on self-synchronized all-optical Compton scattering
Inverse Compton scattering between ultra-relativistic electrons and an intense laser field has been proposed as a major route to generate compact high-brightness and high-energy γ-rays. Attributed to the inherent synchronization mechanism, an all-optical Compton scattering γ-ray source, using one laser to both accelerate electrons and scatter via the reflection of a plasma mirror, has been demo...
متن کاملMeV-energy x rays from inverse compton scattering with laser-wakefield accelerated electrons.
We report the generation of MeV x rays using an undulator and accelerator that are both driven by the same 100-terawatt laser system. The laser pulse driving the accelerator and the scattering laser pulse are independently optimized to generate a high energy electron beam (>200 MeV) and maximize the output x-ray brightness. The total x-ray photon number was measured to be ∼1×10(7), the source ...
متن کاملInverse Compton scattering model for gamma-ray production in MeV blazars
It is proposed that the spectra of so called ’MeV blazars’ can be explained in terms of previously developed models of the external comptonization of accretion disk radiation provided that the structure of the inner and outer parts of the accretion disk is different. The electron acceleration is saturated by the inverse Compton losses in the inner geometrically thick disk and the outer geometri...
متن کاملCompton scattering as a probe for materials investigation
This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.
