Relativistic pair plasmas and jets are believed to exist in many astrophysical objects [Wardle 1998, Weidenspointner 2008] and are invoked to explain energetic phenomena related to Gamma Ray Bursts, Black Holes and the heating of intergalactic medium (IGM) [Mirabel & Rodriguez 1999, Meszaros 2002]. Although short lived, a laboratory source of relativistic pair plasma jets can be used as a surrogate to study the dynamics of pair jet-plasma interactions, such as the evolution of instabilities induced by relativistic pair slowing down in a neutral electron-ion plasma. This is directly applicable to quantifying the heating of the IGM by blazar-produced relativistic pairs and can test the theory that these “pair (jets) are expected to trigger collective plasma instabilities (as opposed to binary Coulomb collisions, that are negligible)” [Sironi & Giannios 2014].
