Recreating outer space plasma systems in the lab is not the latest SAFIRE experiment or more from Anthony Peratt.

... it appears that electric fields may have a significant effect on the dynamics of the electrons, and a very strong electric field trapping the electrons usually forms at the plasma-wall boundary in laboratory plasmas.

It is the news worthy title of the more Tohoku University peer acceptable Adiabatic Expansion of Electron Gas in a Magnetic Nozzle.

Peer reviewed space plasma laboratory experiments The expansion of a gas with no electric charge has typically been studied using traditional thermodynamics. Experiments with simple gases can easily be carried out in laboratories, whereas those involving gaseous plasmas of astrophysical and solar interest pose a number of difficulties.

Observations near the sun and in Earth orbit have been interpreted as a demonstration that solar wind does not expand adiabatically from the sun, as would be expected for this near-collisionless environment. Rather, it expands isothermally, implying that heating of the plasma occurs as it propagates through interplanetary space.

Many laboratory-based experiments under adiabatic conditions have also shown a nearly isothermal expansion in magnetic nozzles and the relation with astrophysical plasmas.

However, in these expanding adiabatic systems, it appears that electric fields may have a significant effect on the dynamics of the electrons, and a very strong electric field trapping the electrons usually forms at the plasma-wall boundary in laboratory plasmas. So what would happen if there were no electric fields trapping the electrons?

yet thermodynamic concepts can be used, with caution, in explaining the results

The observable raw data of electromagnetic forces and plasma should be ok, even if you personally use caution with some peer reviewed interpretations.

And these. The Suns plasma currents, solar winds, excited by magnetic fields? Astrophysical plasmas accelerated by electric fields?

Single, double, multiple layers of plasmas at the wall boundary? How many, few can form?

The measurements were made on collisionless electrons in an argon plasma expanding in a magnetic nozzle.

The collision lengths of all electron collision processes are greater than the scale length of the expansion, meaning the system cannot be in thermodynamic equilibrium, yet thermodynamic concepts can be used, with caution, in explaining the results.
