Laser-Wakefield Electron Beams as Drivers of High-Quality Positron Beams and Inverse-Compton-Scattered Photon Beams

The fast-paced development of laser-wakefield electron acceleration has recently culminated in the generation of electron beams with extreme characteristics, including femtosecond-scale duration,

Expansion of a mildly relativistic hot pair cloud into an electron-proton plasma

The expansion of a charge-neutral cloud of electrons and positrons with the temperature 1 MeV into an unmagnetized ambient plasma is examined with a 2D particle-in-cell (PIC) simulation. The pair

Experimental Observation of a Current-Driven Instability in a Neutral Electron-Positron Beam.

The first experimental observation of a current-driven instability developing in a quasineutral matter-antimatter beam is reported, suggesting the existence of such long-lived magnetic fields can be related to analog astrophysical systems, such as those prevalent in lepton-dominated jets.



Generation of neutral and high-density electron–positron pair plasmas in the laboratory

It is shown that, by using a compact laser-driven setup, ion-free electron–positron plasmas with unique characteristics can be produced, and their charge neutrality, high-density and small divergence finally open up the possibility of studying electron– Positron Plasmas in controlled laboratory experiments.

Scaling the yield of laser-driven electron-positron jets to laboratory astrophysical applications.

New experimental results obtained are reported that show directed laser-driven relativistic electron-positron jets with up to 30 times larger yields than previously obtained and a quadratic dependence of the positron yield on the laser energy.

Laser-driven generation of collimated ultra-relativistic positron beams

We report on recent experimental results concerning the generation of collimated (divergence of the order of a few mrad) ultra-relativistic positron beams using a fully optical system. The positron

An ultra-relativistic electron beam propagating through a high-Z solid triggers an electromagnetic cascade, whereby a large number of high-energy photons and electron–positron pairs are produced

Multidimensional electron beam-plasma instabilities in the relativistic regime

The interest in relativistic beam-plasma instabilities has been greatly rejuvenated over the past two decades by novel concepts in laboratory and space plasmas. Recent advances in this long-standing

Electric field detection in laser-plasma interaction experiments via the proton imaging technique

Due to their particular properties, the beams of the multi-MeV protons generated during the interaction of ultraintense (I>1019 W/cm2) short pulses with thin solid targets are most suited for use as

Plans for the creation and studies of electron–positron plasmas in a stellarator

Electron–positron plasmas are unique in their behavior due to the mass symmetry. Strongly magnetized electron–positron, or pair, plasmas are present in a number of astrophysical settings, such as

Table-top laser-based source of femtosecond, collimated, ultrarelativistic positron beams.

The generation of ultrarelativistic positron beams with short duration, small divergence, and high density from a fully optical setup is reported, and the detected positron beam propagates with high-density electron beam and γ rays, thus closely resembling the structure of an astrophysical leptonic jet.

High energy density laboratory astrophysics

High energy density (HED) physics refers broadly to the study of macroscopic collections of matter under extreme conditions of temperature and density. The experimental facilities most widely used

Spectral and spatial characterisation of laser-driven positron beams

The generation of high-quality relativistic positron beams is a central area of research in experimental physics, due to their potential relevance in a wide range of scientific and engineering areas,
