A tunable plasma-based energy dechirper
R. D'Arcy, S. Wesch, A. Aschikhin +23
A tunable plasma-based energy dechirper has been developed at FLASHForward to remove the correlated energy spread of a 681~MeV electron bunch. Through the interaction of the bunch…

Direct Measurement of Focusing Fields in Active Plasma Lenses
J. -H. Röckemann, L. Schaper, S. K. Barber +17
Active plasma lenses have the potential to enable broad-ranging applications of plasma-based accelerators owing to their compact design and radially symmetric kT/m-level focusing f…

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…
