Resonant Plasma/New ICF method

In summary, the conversation discusses using a high voltage device and an alternating current to create a magnetic field that would confine plasma in a tube. The idea is similar to a Z-Pinch device, but with the added element of using a resonant frequency to create antinodes for confinement. However, the feasibility of this idea is uncertain due to the need for a constant or increasing magnetic field and the challenge of heating the plasma to the necessary high temperatures for fusion. Additionally, the use of optical lasers for heating may not be effective due to the transparency of high temperature plasmas.

Alright, I've been looking around for an opinion on this for awhile:

Suppose you have a tube of deuterium whose radius is much much less then the length. You use a high voltage/large current to ionize this Deuterium. In a similar configuration to the Z-Pinch device a magnetic field is created. Here's what I wish to do, but have no idea if It would work.

Let's assume that I hook a high voltage device up to a function generator and modulate the frequency of the AC current, which then creates and magnetic field, which then will be alternated at the resonant frequency of the tube, causing the Plasma to move at the resonant freqency, which would then confine the gas into antinodes just like if a speaker would if it was put at the beginning of the tube. The only thing that is different is that I would have to account for the tube being closed-closed.

Confined Plasma could then be confined to the center by using a pulse type ac current, which then could be bomarded by a laser blah blah.


Decent Idea? Has anyone done this? Is it feasible?

Thanks!

An alternating current usually implies a sinusoidal current in with the current (and magnetic field) reverse polarity sinusoidally. Most plasma heating systems would use a pulsed or DC current such that the magetic field does not switch polarity during operation.

The main issue is that fusion requires high temperatures, which also means high plasma pressures, which means a confining magnetic field must be relatively constant or increasing in response to the plasma pressure, in order to maintain confinement.

High temperature plasmas (nuclei and electrons) are transparent to optical lasers. Besides ohmic heating from induced electrical current, plasmas may be heated by radiofrequency EM waves, or neutral beam injection.
