Velocity Dispersion of Correlated Energy Spread Electron Beams in the Free Electron Laser
L. T. Campbell, A. R. Maier
The effects of a correlated linear energy/velocity chirp in the electron beam in the FEL, and how to compensate for its effects by using an appropriate taper (or reverse-taper) of…
Accurate modeling of plasma acceleration with arbitrary order pseudo-spectral particle-in-cell methods
Sören Jalas, Irene Dornmair, Rémi Lehe +4
Particle in Cell (PIC) simulations are a widely used tool for the investigation of both laser- and beam-driven plasma acceleration. It is a known issue that the beam quality can be…
Elimination of Numerical Cherenkov Instability in flowing-plasma Particle-In-Cell simulations by using Galilean coordinates
Remi Lehe, Manuel Kirchen, Brendan B. Godfrey +2
Particle-In-Cell (PIC) simulations of relativistic flowing plasmas are of key interest to several fields of physics (including e.g. laser-wakefield acceleration, when viewed in a L…
Stable discrete representation of relativistically drifting plasmas
Manuel Kirchen, Remi Lehe, Brendan B. Godfrey +5
Representing the electrodynamics of relativistically drifting particle ensembles in discrete, co-propagating Galilean coordinates enables the derivation of a Particle-in-Cell algor…
Chirp mitigation of plasma-accelerated beams using a modulated plasma density
R. Brinkmann, N. Delbos, I. Dornmair +13
Plasma-based accelerators offer the possibility to drive future compact light sources and high-energy physics applications. Achieving good beam quality, especially a small beam ene…
Plasma-driven ultrashort bunch diagnostic
I. Dornmair, C. B. Schroeder, K. Floettmann +2
Ultrashort electron bunches are crucial for an increasing number of applications, however, diagnosing their longitudinal phase space remains a challenge. We propose a new method th…
