摘要

The aim of this work is to provide a relativistically correct characterization for the stability of counterstreamingplasma structures ubiquitous in fusion plasma experiments and astrophysical sources of nonthermal radiation. Here, in thefirst part of this work, a new relativistically correct approach is formulated for the counterstreaming plasmas in thermalequilibrium, on the basis of the relativistic Juttner-Maxwell distribution function and a correct representation of thisdistribution in the laboratory frame of reference by using the appropriate Lorentz transformations for momentum andenergy. The particle velocity resulting from the thermal motion and the bulk displacement of plasma particles is thuslimited according to the relativistic theory to less than c (the speed of light in vacuum). New criteria are derived for theexistence of counterstreams conditioned by the magnitude of their bulk velocity with respect to the thermal speed.Accurate simplified forms of the distribution functions derived here for different limits of the streaming velocity and theplasma temperature, will be invoked in the second part of this work as input to the stability analysis of these systems.
