However, because the properties of these relativistic pair plasmas can depart significantly from those of traditional non-relativistic plasmas studied in the laboratory and in space, our understanding of the basic plasma processes in this frontier regime is still very limited.
In pair plasmas, there is no separation between electron and positron kinetic scales, and this has qualitative implications for the properties of the waves and instabilities that develop in these systems.
The study of basic kinetic collective plasma processes—instabilities, shocks, magnetic reconnection, turbulence—in relativistic, pair-dominated environments is, thus, very important to build a systematic knowledge base for the development of theoretical models and for the interpretation of high-energy astrophysical observations.
In the following, we discuss some of the important requirements for experimental studies of collective processes in relativistic pair plasmas.To enable the study of collective processes in relativistic pair plasmas, laboratory experiments need to meet a set of basic conditions.To study plasma behavior, the minimum scale of the produced pair plasmas needs to be the Debye length,
