ICS Diagnostic of FEL's Electron Beam Based on 6D Wigner Function Approach | |
|

| We report on the design of the Inverse Compton Scattering (ICS) based diagnostic system for the electron beam in the free electron laser. Novel 6D Wigner function ICS theory analytically relates the phase space of emitted radiation to the phase space of the electron beam at the interaction point. Based on this theory, we find signatures of the electron beam phase space features in the emitted ICS radiation. Then, we analyze which of these signatures can be measured in the existing experimental setups and compare reconstructed electron beam phase space features to simulation results from the beam tracking codes. Finally, we inverse the 6D Wigner function ICS theory to find the electron phase space distribution dependence on characteristics of emitted radiation and propose the design of the new diagnostic system to reconstruct desirable 2D projections of the 6D electron phase space. | ||
