A simple method for timing an XFEL source to high-power lasers
Gianluca Geloni, Evgeni Saldin, Evgeni Schneidmiller +1
We propose a technique, to be used for time-resolved pump-probe experiments, for timing an x-ray free electron laser (XFEL) to a high-power conventional laser with femtosecond accu…
Longitudinal impedance and wake from XFEL undulators. Impact on current-enhanced SASE schemes
Gianluca Geloni, Evgeni Saldin, Evgeni Schneidmiller +1
In this article we derive longitudinal impedance and wake function for an undulator setup with arbitrary undulator parameter, taking into account a finite transverse size of the el…
Theory of Nonlinear Harmonic Generation in Free-Electron Lasers with Helical Wigglers
Gianluca Geloni, Evgeni Saldin, Evgeni Schneidmiller +1
Coherent Harmonic Generation (CHG), and in particular Nonlinear Harmonic Generation (NHG), is of importance for both short wavelength Free-Electron Lasers (FELs), in relation with…
Undulator Radiation in a Waveguide
Gianluca Geloni, Evgeni Saldin, Evgeni Schneidmiller +1
We propose an analytical approach to characterize undulator radiation near resonance, when the presence of the vacuum-pipe considerably affects radiation properties. This is the ca…
