    Relativistic high-density quasi-neutral electron-positron (fireball) beams have been recently generated in the laboratory providing a platform to explore processes directly to address unsolved problems in astrophysics. In this work, we present numerical studies, complemented by theoretical estimates, of the interaction of fireball beams with non-zero emittance with plasmas using beam ...

We also show that the longitudinal energy spread, typical of plasma-based accelerated electron-positron fireball beams, plays a minor role in the growth of CFI in these scenarios.

    The current filamentation instability (CFI) is capable of generating strong magnetic fields relevant to the explanation of radiation processes in astrophysical objects and leads to the onset of particle acceleration in collisionless shocks. Probing such extreme scenarios in the laboratory is still an open challenge.

    The interaction of energetic particle beams with plasmas is ubiquitous in laboratory and in astrophysical scenarios, and so are beam-plasma instabilities such as Weibel [], current filamentation [2, 3] and two stream [4, 5].The first two instabilities, also referred as Weibel-like instabilities, are electromagnetic in nature and arise due to the anisotropy in the momentum distribution of the ...
