Enhanced coherent transition radiation from midinfrared-laser-driven microplasmas [PDF]
We present a particle-in-cell (PIC) analysis of terahertz (THz) radiation by ultrafast plasma currents driven by relativistic-intensity laser pulses.

Multistage Positron Acceleration by an Electron Beam-Driven Strong Terahertz Radiation
Laser–plasma accelerators (LPAs) have been demonstrated as one of the candidates for traditional accelerators and have attracted increasing attention due to their compact size, high acceleration gradients, low cost, etc. However, LPAs for positrons still

The structure and glass transition behavior of PLLA under the influence of gamma radiation [PDF]
The influence of gamma radiation on the structure and glass transition behavior of poly-L-lactide (PLLA) has been studied. Since PLLA exposed to high-energy radiation in the presence of air is prone to chain scission reactions and large degradation ...

Photon avalanche in nanoluminophore obtained by REE silicate evaporation
A bulk phosphor composition Sr2Y6.8YbEr0.2Si6O26 was synthesized. A nanophosphorus in an amorphous state was obtained from this sample by the method of pulsed electron beam evaporation.

Optical transition radiation based transverse beam diagnostics for nonrelativistic ion beams
The usage of optical transition radiation (OTR) for profile monitoring of relativistic electron beams is well known. This paper presents the case for beam diagnostic application of OTR for nonrelativistic ion beams.

Coherent transition radiation from attosecond electron pulses [PDF]
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.

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.

We consider analytically and numerically the emission of coherent transition radiation by few-femtosecond and attosecond electron pulses. With optimized geometries based on tilted surfaces we avoid the influences of the beam diameter and velocity ...

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