Description
The interaction between photons and electrons is a well-studied phenomenon known as Compton scattering. Based on this mechanism, Compton light sources operating in the x-ray and gamma-ray regions have been developed by colliding a laser beam with an electron beam. One such example is the High-Intensity Gamma Source (HI$\gamma$S) at Triangle Universities Nuclear Laboratory (TUNL). Resonant interaction between photons and atomic systems, such as hydrogen-like ions, has orders of magnitude higher cross-section compared to the electron-photon interaction. Recently, researchers have proposed the Gamma Factory initiative at CERN to take advantage of ultra-relativistic stripped ion beams to generate an intense gamma-ray beam with unprecedentedly high flux. In this work, we will present a simple semi-classical model of a damped-driven oscillator to describe the behavior of resonant Compton scattering. We will discuss the underlying physics of very large resonant total scattering and a few limitations associated with resonant behavior, such as the energy-matching conditions and efficiency of beam-beam scattering. We will also present a framework to develop a simulation code for resonant Compton Scattering.
