FOCUS: fast Monte Carlo approach to coherence of undulator sources / Siano, M (Milan U. ; INFN, Milan) ; Geloni, G (European XFEL, Hamburg) ; Paroli, B (Milan U. ; INFN, Milan) ; Butti, D (CERN) ; Lefèvre, T (CERN) ; Mazzoni, S (CERN) ; Trad, G (CERN) ; Iriso, U (CELLS - ALBA, LLS) ; Nosych, A A (CELLS - ALBA, LLS) ; Torino, L (CELLS - ALBA, LLS) et al.
FOCUS (Fast Monte CarlO approach to Coherence of Undulator Sources) is a new GPU-based simulation code to compute the transverse coherence of undulator radiation from ultra-relativistic electrons. The core structure of the code, which is written in the language C++ accelerated with CUDA, combines an analytical description of the emitted electric fields and massively parallel computations on GPUs.

We present Fast Monte-CarlO approach to Coherence of Undulator Sources (FOCUS), a new GPU-based code to compute the transverse coherence of X-ray radiation from undulator sources. The code relies on scaled dimension- less quantities and analytic expressions of the electric field emitted by electrons in an undulator. [...]

Benchmark of ASTRA with Analytical Solution for the Longitudinal Plasma Oscillation Problem / Geloni, Gianluca ; Saldin, Evgeny L ; Schneidmiller, Evgeny A ; Yurkov, Mikhail V
During the design of X-FELs, space-charge codes are required to simulate the evolution of longitudinal plasma oscillation within an electron beam in connection with LSC microbunching instability [1] and certain pump-probe synchronization schemes [2]. In the paper [3] we presented an analytical solution to the initial value problem for longitudinal plasma oscillation in an electron beam. [...]

A 3D Self-Consistent, Analytical Model for Longitudinal Plasma Oscillation in a Relativistic Electron Beam / Geloni, G ; Saldin, E L ; Schneidmiller, E ; Yurkov, M V
Longitudinal plasma oscillations are becoming a subject of great interest for XFEL physics in connection with LSC microbunching instability[1] and certain pump-probe synchronization schemes[2]. In the present paper we developed the first exact analytical treatment for longitudinal oscillations within an axis-symmetric, (relativistic) electron beam, which can be used as a primary standard for benchmarking space-charge simulation codes.

Misconceptions regarding Second Harmonic Generation in X-Ray Free-Electron Lasers / Geloni, G ; Saldin, E L ; Schneidmiller, E ; Yurkov, M V
Nonlinear generation of coherent harmonic radiation is an important option in the operation of a X-ray FEL facility since it broadens the spectral range of the facility itself, thus allowing for a wider scope of experimental applications. We found that up-to-date theoretical understanding of second harmonic generation is incorrect. [...]
