The fundamental coherent radiation emission processes from a bunched charged particles
beam are outlined. In contrast to spontaneous emission of radiation from a random electron …

Accelerator-based light sources such as storage rings and free-electron lasers use
relativistic electron beams to produce intense radiation over a wide spectral range for …

Photon number distributions of classical and non-classical light sources have been studied
extensively, yet their impact on photoemission processes is largely unexplored. In this …

When multiple quantum emitters radiate, their emission rate may be enhanced or
suppressed due to collective interference in a process known as super-or subradiance …

In this paper we describe a new microbunching instability occurring in charged particle
beams propagating along a straight trajectory. The nature of these exponentially growing …

Operation of a Quantum Free Electron Laser (QFEL) could provide a compact and fully
coherent source of X-and γ-rays. Imperative to experimental realization is allowing for …

Coulomb interaction between charged particles is a well-known phenomenon in many areas
of research. In general, the Coulomb repulsion force broadens the pulse width of an electron …

Coherent electron cooling is a promising technique to cool high-intensity hadron bunches by
imprinting the noise in the hadron beam on a beam of electrons, amplifying the electron …

We review physical mechanisms and driving forces behind the microbunching instability in
modern free-electron lasers. Laser heater and alternative methods to fight the instability are …

The evolution of picosecond modulations of the longitudinal profile of an electron beam
generated in an rf photoinjector is analyzed and optimized with the goal of obtaining high …
