Description
The systematic comparison of two semi-analytical models of microbunching instability affecting electron beams in single pass or recirculating linear accelerators is reported. The comparison is comprehensive of numerous features of the instability, and enriched by three different expressions to calculate intrabeam scattering. The inclusion of this effect allows the recovery of agreement with published experimental observations, to date either in disagreement with theory, or in partial agreement by virtue of blind fitting of parameters. The work is supported by recent experimental sessions at FERMI FEL, on control of microbuching instability in single vs. double compression.
