We describe here efforts to create and study magnetized electron–positron pair plasmas, the
existence of which in astrophysical environments is well-established. Laboratory …

Linear gyrokinetic simulations of magnetically confined electron–positron plasmas are
performed for the first time in the geometry and parameter regimes likely to be relevant for …

Dipole and stellarator geometries are capable of confining plasmas of arbitrary neutrality,
ranging from pure electron plasmas through to quasineutral. The diocotron mode is known …

A generalized linear dispersion relation of electromagnetic slab universal modes is derived,
taking into account arbitrary ion charge state, electron finite Larmor radius (FLR) effects, and …

In this paper, we summarize our recent work on gyrokinetic applications in electron–positron
and non-neutral plasma. The electrostatic stability of electron–positron plasmas was …

The model of the global gyrokinetic particle-in-cell code ORB5 has been extended for the
study of pair plasmas. This has been done by including the physics of the Debye shielding …

Interchange instabilities are a critical issue for confinement and transport in (otherwise
exceptionally stable) planned magnetically confined quasi-neutral electron-positron plasma …

To cope with the challenges of the complex completion of Wendelstein 7-X, a dedicated
project (“Wendelstein 7-X/C”) was set up as a separate organisational structure besides the …
