Coherent superposition of orthogonal modes
Klaus Floettmann
The coherent superposition of orthogonal modes can result in transverse offsets, variations of the Rayleigh length and a reduction of the beam quality factor of the coherent sum of…
Equivalence of Gouy and Courant-Snyder phase
Klaus Floettmann
The generation of electron vortex beams and the conversion of these beams into beams without angular momentum by means of astigmatic optical systems, or vice versa, has been pursue…
Quantum mechanical formulation of the Busch theorem
Klaus Floettmann, Dmitry Karlovets
Electron vortex beams offer unique opportunities for the study of chiral or magnetic structures in electron microscopes and of fundamental effects of quantum interference in partic…
Superradiant Cherenkov-Wakefield radiation as THz source for FEL facilities
Klaus Floettmann, Francois Lemery, Martin Dohlus +3
An electron beam passing through a tube which is lined on the inside with a dielectric layer will radiate energy in the THz range due to the interaction with the boundary. The reso…
Plasma Lenses: Possible alternative OMD at the ILC
Manuel Formela, Niclas Hamann, Klaus Floettmann +3
In the baseline design of the International Linear Collider (ILC) an undulator-based source is foreseen for the positron source in order to match the physics requirements. The rece…
Fundamental characteristics of transverse deflecting field
Valentin Paramonov, Klaus Floettmann
The Panofsky-Wenzel theorem connects the transverse deflecting force in an rf structure with the existence of a longitudinal electric field component. In this paper it is shown tha…
