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…

Optical approximation in the theory of geometric impedance

G. Stupakov, K. L. F. Bane, I. Zagorodnov

In this paper we introduce an optical approximation into the theory of impedance calculation, one valid in the limit of high frequencies. This approximation neglects diffraction ef…

Spin motion at and near orbital resonance in storage rings with Siberian Snakes. Part I: at orbital resonance

D. P. Barber, M. Vogt

Here, and in a sequel, we invoke the invariant spin field to provide an in--depth study of spin motion at and near low order orbital resonances in a simple model for the effects of…

Longitudinal Wake Field for an Electron Beam Accelerated through a Ultra-High Field Gradient

Gianluca Geloni, Evgeni Saldin, Evgeni Schneidmiller +1

Electron accelerators with higher and higher longitudinal field gradients are desirable, as they allow for the production of high energy beams by means of compact and cheap setups.…

Coherence properties of the radiation from X-ray free electron laser

E. L. Saldin, E. A. Schneidmiller, M. V. Yurkov

We present a comprehensive analysis of coherence properties of the radiation from X-ray free electron laser (XFEL). We consider practically important case when XFEL is optimized fo…
