In traditional electron/ion laboratory plasmas, the system size L is much larger than both the plasma skin depth ls and the Debye length \unicode[STIX]x1D706D . In current and planned efforts to create electron/positron plasmas in the laboratory, this is not necessarily the case. A low-temperature, low-density system may have \unicode[STIX]x1D706D<L<ls ; a high-density, thermally relativistic system may have ls<L<\unicode[STIX]x1D706D . Here we consider the question of what plasma physics phenomena are accessible (and/or diagnostically exploitable) in these different regimes and how this depends on magnetization. While particularly relevant to ongoing pair plasma creation experiments, the transition from single-particle behaviour to collective, ‘plasma’ effects – and how the criterion for that threshold is different for different phenomena – is an important but often neglected topic in electron/ion systems as well.
