The total x-ray photon number was measured to be 1 Ã 10 7, the source size was 5 m, and the beam divergence angle was 10 mrad. Furthermore, the developed tool can be easily embedded in a geant4 user application for the tracking of photons generated through inverse Compton scattering in a given experimental setup. 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 code produces results in agreement with cain, one of the most used Monte Carlo tools, for a wide range of interaction conditions at a computational time reduced by 2 orders of magnitude. Here, we present a novel Monte Carlo code based on geant4 for the simulation of inverse Compton scattering in the linear regime. Each of these tools has strengths and weaknesses. To delineate regimes (ff-emission)- several characteristic frequencies: For x< x0 scattering will be unimportant however x> x0 scattering will modify the spectrum For x> xt absorption is unimportant in range x0Different computational tools have been developed for this task, based on both a purely analytical treatment and Monte Carlo simulation codes. coh, frequency at which incoherent (inverse Compton) scattering can be important. The angles and frequencies of the photon as seen by the moving electron are different than what is measured in the lab frame. The standard Compton equations are valid only from the electronâs rest frame. To find the final energy of the photon, we must perform a couple Lorentz transformations. Regardless of the specific application, a reliable tool for the simulation of the radiation produced is essential for the design, the commissioning, and, subsequently, the study and optimization of this kind of source. Mathematical Derivation of Inverse Compton Scattering. Different interaction layouts are possible for electron and laser beams, and several applications are being studied, ranging from fundamental research in nuclear physics to advanced x-ray imaging in the biomedical field, depending on the radiation energy range, intensity, and bandwidth. Photon sources based on inverse Compton scattering, namely, the interaction between relativistic electrons and laser photons, are emerging as quasimonochromatic energy-tunable sources either as compact alternatives to synchrotron facilities for the production of low-energy (10â100 keV) x rays or to reach the 1â100 MeV photon energy range, which is inaccessible at synchrotrons.
