Wigner Rotation: Theory and Application to Practical Relativistic Engineering Problems
Evgeni Saldin
The standard expression for the Wigner rotation leads to incorrect result for the wavefront rotation. The results for the Wigner rotation in the Lorentz lab frame obtained by many…
Effects of energy spread on Brightness and Coherence of undulator sources
Gianluca Geloni, Svitozar Serkez, Ruslan Khubbutdinov +2
The (spectral) brightness for partially transverse coherent sources as Synchrotron Radiation (SR) and Free-Electron Laser (FEL) sources can be defined as the maximum of the Wigner…
Relativity and Accelerator Engineering
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
From a geometrical viewpoint, according to the theory of relativity, space and time constitute a four-dimensional continuum with pseudo-Euclidean structure. This has recently begun…
On Radiation Emission from a Microbunched Beam with Wavefront Tilt and Its Experimental Observation
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
In this paper we compare experimental observations and theory of radiation emission from a microbunched beam with microbunching wavefront tilt with respect to the direction of moti…
Opportunities for Two-color Experiments at the SASE3 undulator line of the European XFEL
Gianluca Geloni, Vitali Kocharyan, Tommaso Mazza +3
X-ray Free Electron Lasers (XFELs) have been proven to generate short and powerful radiation pulses allowing for a wide class of novel experiments. If an XFEL facility supports the…
Radiation by Moving Charges
Gianluca Geloni, Vitali Kocharyan, Evgeni Saldin
It is generally accepted that the dynamics of relativistic particles in the lab frame can be described by taking into account the relativistic dependence of the particles momenta o…
