Longitudinal Bunch Diagnostics using Coherent Transition Radiation Spectroscopy
Bernhard Schmidt, Stephan Wesch, Toke Kövener +4
The generation and properties of transition radiation (TR) are thoroughly treated. The spectral energy density, as described by the Ginzburg-Frank formula, is computed analytically…
Femtosecond profiling of shaped X-ray pulses
M. C. Hoffmann, I. Grguraš, C. Behrens +20
Arbitrary manipulation of the temporal and spectral properties of X-ray pulses at free-electron lasers (FELs) would revolutionize many experimental applications. At the Linac Coher…
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…
The FLASHForward Facility at DESY
A. Aschikhin, C. Behrens, S. Bohlen +35
The FLASHForward project at DESY is a pioneering plasma-wakefield acceleration experiment that aims to produce, in a few centimetres of ionised hydrogen, beams with energy of order…
Electron beam profile imaging in the presence of coherent optical radiation effects
Christopher Behrens, Christopher Gerth, Gero Kube +3
High-brightness electron beams with low energy spread at existing and future x-ray free-electron lasers are affected by various collective beam self-interactions and microbunching…
Constraints on photon pulse duration from longitudinal electron beam diagnostics at a soft X-ray free-electron laser
C. Behrens, N. Gerasimova, Ch. Gerth +5
The successful operation of X-ray free-electron lasers (FELs), like the Linac Coherent Light Source or the Free-Electron Laser in Hamburg (FLASH), makes unprecedented research on m…
Reversible electron beam heating for suppression of microbunching instabilities at free-electron lasers
Christopher Behrens, Zhirong Huang, Dao Xiang
The presence of microbunching instabilities due to the compression of high-brightness electron beams at existing and future X-ray free-electron lasers (FELs) results in restriction…
Generation and Characterization of Electron Bunches with Ramped Current Profiles in a Dual-Frequency Superconducting Linear Accelerator
P. Piot, C. Behrens, C. Gerth +5
We report on the successful experimental generation of electron bunches with ramped current profiles. The technique relies on impressing nonlinear correlations in the longitudinal…
