| Title | Analysis of Microbunching Structures in Transverse and Longitudinal Phase Spaces | ||||
| Abstract | Microbunching instability (MBI) has been a challenging issue in high-brightness electron beam transport for modern accelerators. Our Vlasov analysis of MBI is based on single-pass configuration. For multi-pass recirculation or a long beamline, the intuitive argument of quantifying MBI, by successive multiplication of MBI gains of sub-beamline sections, was found to underestimate the effect. More thorough analyses based on concatenation of gain matrices aimed to combine both density and energy modulations for a general beamline. Yet, quantification still focuses on characterizing longitudinal phase space; microbunching structures residing in (x,z) or (x¿,z) was observed in particle tracking simulation. Inclusion of such cross-plane microbunching structures in Vlasov analysis shall be a crucial step to systematically characterize MBI for a beamline complex in terms of concatenating individual beamline segments. We derived a semi-analytical formulation to include the microbunching structu | ||||
