Abstract

We apply a recently developed Vlasov solver to the study of the microbunching instability generated by shot noise in the beam delivery systems of x-ray free electron lasers (FELs). We discuss two lattices presently under consideration for the FEL Fermi project at Elettra and show that at least one of the two lattices appears capable of delivering a beam with the desired quality in the longitudinal phase space.

  2. Simulations with a number of macroparticles equal to the bunch population are within reach, though. A 1B macroparticle simulation with application to the Fermi project has been demonstrated [21]. However, the required computing resources for these simulations are considerable, limiting their extensive use for lattice design and optimization.
