Analysis of Plasma Detachment through Magnetic Nozzle via Canonical Field Theory

Abstract

In this paper, I have investigated the mechanism of plasma detachment through magnetic nozzle via canonical field theory, especially by considering canonical vorticity flux $\Psi_{\sigma}$ contour and dissipative force $\vec{R}_{\sigma}$. As one of the most recent experimental proofs of plasma detachment, Olsen et al\cite{Olsen}., observed and investigated three key indications of plasma detachment. However, after solving for numerical fits with their experimental data, I found that constant ion flux lines did not actually separate from constant magnetic flux lines. Thus, their first key indication becomes incorrect now. Whereas, my analytical results are consistent with the other two key indications. At the beginning, plasma detached from canonical vorticity flux contours due to non-zero dissipative force and attached on magnetic flux lines instead. However, $\vec{R}_{\sigma} \simeq 0$ force makes plasma re-attach on canonical vorticity flux contours around the plume edge region. As the most significant and notable result through my analysis, I confirmed the existence of returning plasma flow around the plume edge region.
