Longitudinal phase space diagnostics with a nonmovable corrugated passive wakefield streaker

P Dijkstal, W Qin, S Tomin - Physical Review Accelerators and Beams, 2024 - APS
Time-resolved diagnostics at free-electron laser (FEL) facilities, in particular electron beam
longitudinal phase space (LPS) and FEL power profile measurements, provide information …

[HTML][HTML] Bounds on geometric wakefields in collimators and step transitions of arbitrary cross sections

LA Shaposhnikov, SS Baturin - Physics of Plasmas, 2024 - pubs.aip.org
We present the wakefield conformal mapping technique that can be readily applied to the
analysis of the radiation generated by an ultra-relativistic particle in the step transition and a …

Beam wakes for canonical chambers with anisotropic surface impedance

I Zagorodnov, M Dohlus - Physical Review Accelerators and Beams, 2023 - APS
We consider analytical expressions for beam impedance of round, rectangular, and Π-
shaped waveguides with anisotropic surface impedance of arbitrary nature. The formulas …

Geometric wakes in collimators and step transitions of arbitrary cross-sections: conformal mapping approach

LA Shaposhnikov, SS Baturin - arXiv preprint arXiv:2308.01235, 2023 - arxiv.org
In the present study, we extend the approach of the wake field conformal mapping technique
to the case of the step transition and a collimator. We assume that all pipes have different …
