Plasma vortices and Pinches

Thanks again, Doug Lindstrom did his Master’s Thesis on pinches, and all these results are contained within the wavefunction. I encourage AIAS Fellows to apply the ECE theory to results. In this case the application can be done with the suggestion sent to Horst recently of producing an animation in which the parameters can be varied. Horst is on holiday at present. We have already produced pinches, ring structures, filaments,flows and so on. It is now simply a matter of applying the theory to the experimental data, as I have always done in forty three years of research (1971 to 2014). This is very much easier now than in 1971 (hand drawn graphs, hand calculators, deafening paper tape punch, cards and poisonous cyanogen).

Subj: Plasma vortices and Pinches

Myron Horst Here’s a quote from the accompanying link. Norman

“Several researchers observed the rotation in plasma produced by theta
pinches, and they put forward various hypotheses to explain the origin of
this rotation1″6. An intensive experimental investigation of conical theta
pinches by Wells in 19627 revealed that the observed rotation inside the
pinch coil was associated with a radial electric field (There was no rigid
body rotation) and that the plasma in the throat of the theta pinch had a
net positive potential. Another investigation by Wells8″9 was concerned
with plasma structures produced by a conical theta-pinch coil placed
inside a magnetic guide field. Using magnetic probes, Wells determined
that the plasma geometry of these structures was toroidal, with a 1,000
gauss trapped poloidal field and 200 gauss trapped toroidal field. A 25
KV theta-pinch coil was used with a 2.5 microsecond quarter cycle rise
time and a 4,000 gauss solenoidal guide field. It was first speculated in
the report on this work that this plasma structure was a plasma vortex
ring, but the theory of this vortex formation was not developed until late
The following sections will deal with the process of the development
and elaboration of this theory and its experimental confirmations.
Since 1962, various researchers and laboratories have reported ordered
plasma motion that can be classified as vortex phenomena. In
addition to the initial report and subsequent confirmations by Wells, et
al.7″14, vortex structures have been reported by Farber, Prior, and
Bostick15, Hogberg and Vogel16, Waniek17, Komilkov, et al.18, Komen et
al.19, and Jones and Miller20.
Before going into the details of plasma vortex structures produced in a
conical theta pinch, we will present an abbreviated review of vortex
formation and development in general.
