Coherent transition radiation from attosecond electron pulses [PDF]

open access: yesEPJ Web of Conferences, 2019
We show theoretically and by simulations how coherent transition radiation from tilted surfaces can be used for characterization of attosecond free-electron pulses such as used for pump-probe electron microscopy and diffraction.

Quantum theory of transition radiation and transition pair creation [PDF]

open access: yes, 1998
Theory of the transition radiation and the transition pair creation is developed in the frame of QED. The spectral-angular distributions of probability of the transition radiation and of the transition pair creation are found.

Terahertz Pulse Generation in Underdense Relativistic Plasmas: From Photoionization-Induced Radiation to Coherent Transition Radiation. [PDF]

open access: yesPhysical Review Letters, 2017
Terahertz to far-infrared emission by two-color, ultrashort optical pulses interacting with underdense helium gases at ultrahigh intensities (>10^{19}  W/cm^{2}) is investigated by means of 3D particle-in-cell simulations. The terahertz field is shown to

Image of the transverse bunch profile via coherent optical transition radiation

open access: yesPhysical Review Accelerators and Beams, 2020
The use of optical transition radiation (OTR) monitors is a standard technique to measure transverse beam profiles at many electron accelerators. With modern accelerator technology it is possible to produce and accelerate even ultrashort electron bunches

Longitudinal charge distribution measurement of nonrelativistic ion beams using coherent transition radiation

open access: yesPhysical Review Accelerators and Beams, 2022
Longitudinal charge profile measurements or bunch shape measurements are a challenge for temporally short nonrelativistic bunches. The field profile has a larger longitudinal extent compared to the charge profile for such beams.

Transition Radiation as a Probe of the Chiral Anomaly. [PDF]

open access: yesPhysical Review Letters, 2018
A fast charged particle crossing the boundary between chiral matter and vacuum radiates transition radiation. Its most remarkable features-the resonant behavior at a certain emission angle and the circular polarization of the spectrum-depend on the ...

Performance of the ATLAS Transition Radiation Tracker in Run 1 of the LHC: tracker properties [PDF]

open access: yes, 2017
The tracking performance parameters of the ATLAS Transition Radiation Tracker (TRT) as part of the ATLAS inner detector are described in this paper for di ff erent data-taking conditions in proton–proton, proton–lead and lead–lead collisions at the Large ...

Coherent radiation from neutral molecules moving above a grating [PDF]

open access: yes, 2001
We predict and study the quantum-electrodynamical effect of parametric self-induced excitation of a molecule moving above the dielectric or conducting medium with periodic grating.

Phenomenology of transition radiation at radio frequencies from ultrahigh-energy showers

open access: yesEPJ Web of Conferences, 2017
We explore transition radiation at MHz-GHz frequencies as a possible way to detect ultrahigh-energy (UHE) particles. We have developed a general method to calculate transition radiation that extends the well-known Zas-Halzen-Stanev (ZHS) algorithm.

Longitudinal wakes of a short magnet, coherent transition radiation, and coherent diffraction radiation for an ultrarelativistic electron bunch

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2008
The longitudinal wake is calculated for a bunch of ultrarelativistic electrons that is deflected by a magnet that is much shorter than the formation length of its coherent synchrotron radiation. Using this wake and the Coulomb field of an image bunch, we
