Pair-beam propagation in a magnetised plasma for modelling the polarized radiation emission from gamma-ray bursts in laboratory astrophysics experiments
Ujjwal Sinha, Naveen Kumar
The propagation of a relativistic electron-positron beam in a magnetized electron-ion plasma is studied, focusing on the polarization of the radiation generated in this case. Speci…
Magnetized Current Filaments as a Source of Circularly Polarized Light
U. Sinha, J. Martins, J. Vieira +3
We show that the Weibel or currente filamentation instability can lead to the emission of circularly polarized radiation. Using particle-in-cell (PIC) simulations and a radiation p…
Polarized light from the transportation of a matter-antimatter beam in a plasma
Ujjwal Sinha, Christoph H. Keitel, Naveen Kumar
A relativistic electron-positron beam propagating through a magnetized electron-ion plasma is shown to generate both circularly and linearly polarized synchrotron radiation. The de…
Plasma based helical undulator for controlled emission of circularly and elliptically polarised betatron radiationJ. Vieira, J. Martins, U. Sinha
J. Vieira, J. Martins, U. Sinha
We explore a plasma based analogue of a helical undulator capable of providing circularly and elliptically polarised betatron radiation. We focus on ionisation injection configurat…
