Abstract

The intensity and energy spatial distributions of collimated laser Compton scattering (LCS) γ\gamma-ray beams and of the associated bremsstrahlung beams have been investigated as functions of the electron beam energy, electron beam phase space distribution, laser optics conditions and laser polarization. We show that the beam halo is affected to different extents by variations in the above listed parameters. In the present work, we have used laser Compton scattering simulations performed with the \texttt{eliLaBr} code (https://github.com/dan-mihai-filipescu/eliLaBr) and real LCS and bremsstrahlung γ\gamma-ray beams produced at the NewSUBARU synchrotron radiation facility. A 500~μ\mum MiniPIX X-ray camera was used as beamspot monitor in a wide γ\gamma-ray beam energy range between 1.73~MeV and 38.1~MeV.
