Some Technical Details

One single layer of magnetic field lines in an isolated magnet. (conceptualized)
Though this is a bent dipole magnet, there seems to be no null field in the center because of its asymmetry respecting two separate dipole magnets facing each other like in a Biconic Cusp configuration.






      
The resulting magnetic flux is concentrated at the central area where the magnetic field is weaker, a very necessary condition for the "low field seeking particles"
(conceptualized)







Model: A 3.0


            
 
           
 
                    magnets input sequence: A B C
                    conceptualized wave pattern

AC Mode

circular input sequence (clockwise as seen from above the device) of three-phase alternating current.

internal primay coils: (see first image above)
balanced and symmetrical inner B-field lines, though with alternating polarity and variable magnetic strenght.

external secondary virtual coils: imbalanced and asymmetrical inner B-field lines, since they are “shared coils” that depend on two different magnets with different phases of energy input.

due to the difference between the inner B-field lines of the three primary coils (stable, balanced and symmetrical) and those of the three secondary virtual coils (unstable, imbalanced and asymmetrical), it seems that this device cannot behave in the same way as a conventional hexapole, though this is its apparent configuration, because of the three-phase alternating current applied to its magnets in a circular sequence and the different effects produced in this way over the interactions of their magnetic fields.

DC Mode

All three magnets with a same polarity.

This is probably a much more feasible working version, if taken as a Magnetic Grid for an Inertial Electrostatic strategy as well as an ion magnetic confinement configuration susceptible of applying two converging Laser beams on the vertical axis to facilitate the ignition process of the D-T mixture.


Model: A 4.0



      

   



           magnets input sequence: A B C D
           conceptualized wave pattern

AC Mode

It would probably produce better results than previous A 3.0 model, due to the wave pattern symmetry, seeming to produce some plasma spin too

The only difference in this configuration is that a four-phase alternating current is applied to the magnets to produce a similar result.

Due to the alternating interaction of pairs of magnets, this model seems to behave like two combined quadrupoles in a rotating configuration.

DC Mode

Probably producing similar results to those of previous A 3.0 model.




Model: A 5.0


       






AC Mode 

        magnets input sequence: A B C D E
        conceptualized wave pattern

         alternative sequence for magnets input power: B
         five-pointed star pattern (enhanced frequency)

five-phase alternating current is the main difference for this configuration.

though this is a much more complex frequency pattern, just like in the two previous models (A 3.0 wave pattern is much easier to analyze) it seems there’s a constant alternating combination of positive pulses for every combination of negative pulses, and vice versa. therefore, since this occur in a fast circular sequence, which could be the resulting B-field at the center of these devices? and which could be the trajectories of the charged particles into these magnetic fields, considering that they don't change their direction as fast as the magnets change their polarity, since these particles have a mass and an inertial movement as a result of their magnetically induced speed? 

DC Mode

Too wide diverging B-field areas in the form of cusps (virtual magnets) produced between the main magnets.
This would probably produce confinement problems.

Some Hypotheses

Since these are very complex configurations designed to work with multi-phase wave patterns of alternating current (given its symmetry, A 4.0 seems to be the most coherent one, since A 3.0 may present some problems in comparison), some unforeseen magnetic interactions could still appear to hinder their operation. Moreover, while lacking of a proper 3D simulation software for plasma modeling and some lab testing and physical feedback for a deeper analysis, we can only manage with suppositions, just like, for example, the following ones:

— A multi-phase alternating current allows to increase the wavelenght for each phase while keeping a good frequency of energy input for the whole system, and this may be needed to relatively counteract the magnets inductance. 

— The charged particles would be driven towards the central area of these devices, since this is where their magnetic field is weaker, and a multi-phase alternating current would provide a rotating magnetic pulse seeming to prevent the ions from flowing outwards through the secondary virtual coils because of their asymmetrical inner B-field lines respecting to those of the primary coils. 

— In these configurations, the plasma would be like a free rotor, while the magnets would be like a helical stator with a double function: to ensure the confinement of the ions at the central area of these configurations and to accelerate and compress the mixture of charged particles, contributing to ionize the D-T fuel and to overcome their repulsive electrostatic forces. In addition to a compressive strategy, these devices seem to provide an inertial strategy too based on the approximately radial acceleration of the positive nuclei and their constant change of direction due to the multi-phase alternating current applied to the magnets, probably leading in this way the charged particles to a confinement area.

— A multi-phase alternating current would produce a plasma spin, as a result of the circular sequence of power input applied to the magnets, probably driving in this way the positive nuclei to confinement with a roughly spherical form. 

— Since these devices have been conceived to work with alternating current, a balanced relation between high-frequency and high-current is needed to provide an as coherent as possible rotating B-field at their central area, but this author still ignores whether these two combined values are possible.

— It’s needed to study a resonant LC circuit (inductor and capacitor) using highly conductive coils and supercapacitors with balanced values to achieve the proper frequency. Since a series resonant LC circuit provides voltage magnification and a parallel resonant LC circuit provides current magnification, this second option seems to be better to produce the necessary B-field at the core of the devices while keeping the same voltage.

— Question acould an electric arc of alternating current, or two converging Laser beams, be applied at the central vertical axis of the three devices to facilitate the D-T mixture heating and the ignition process, in the AC Mode as well as in the DC Mode?

— Question b: given that alternating current may produce some operational problems, for instance, with the A 3.0 model, could direct current be also used to work with this improved geometry for Inertial Electrostatic Confinement ?
