Sergio,
OK your diagram and for the way to ionize and to accelerate the plasma. Now about your "centripetator", I suppose that a vertical magnetic field is necessary to make turn the charges. Do you confirm?
The plasma will be somewhat confined in the torus so the ions density will increase up to a certain value function of the confinement quality (a priori low with a sole magnetic field).
Now, let's suppose that the plasma speed be equal to 100 km/s. The energy per ion will be equal to about 100 eV. The problem is that the fusion cross section at 100 eV is extremely weak for D/D ( or D/T). Consequently, the probability to fuse is not nil but extremely low (much lower than for a Fusor).

I am very happy because I have found an appropriate forum to present my arguments, since there are highly educated people here with vast knowledge of nuclear fusion.
In my centripetation system there is no need for a vertical magnetic field to rotate the plasma, the plasma enters possessing enormous kinetic energy, the plasma will tend to continue forward once it is shot out of the cannon, but like the inner wall of the centripetator is curved then the plasma will tend to bend by force in the direction of advance until it curves on itself once it reaches the muzzle where plasma continues to come out, therefore the plasma is subjected to the centripetal force of the cannon but is also subjected to to the centrifugal effect, which in this case is less than the centripetal force, these two forces in opposition must make the plasma tighten on itself more and more as it gets closer to the center.
Patrick Lindecker I cannot deny that a plasma welding arc can generate temperatures that reach 10,000 to 20,000 degrees Kelvin, which is equivalent to an energy of 100 to 200 electron volts, which is several orders below the imperative needs. when creating fusion reactions.
To increase the Kelvin in a plasma, there are several strategies that can be implemented, including:
Increasing Electrical Current: Increasing the electrical current flowing through the plasma can increase its temperature.
Increase the pressure: Increasing the pressure in the plasma can help increase its temperature.
Improve Plasma Confinement: Better plasma confinement can help increase its temperature by preventing heat dissipation.
Optimizing Plasma Composition: By optimizing plasma composition, its temperature can be increased by improving its ability to retain heat.
In the device that I have first devised there is an auxiliary ignition system which creates a first deflagration of low speed plasma, I have attached some images of the system above, the plasma created with this auxiliary system has very little energy as it has a large inductance in series with the electrolytic capacitor, it is only the first stage where a pressurized deuterium gas is converted into a slightly accelerated plasma state.
The consecutive stages are modular plasma accelerators in series.
Each stage consists of 2 parallel neodymium magnets, ceramic spacers and parallel flat electrodes and a non-electrolytic capacitor of 4Kv 2 uf.
The first accelerating stage is automatically activated by passing the plasma created in the previous ignition circuit.
the plasma is accelerated on the one hand thanks to the energy absorbed by the discharge of the capacitor which increases its temperature and volume in an extremely short time and on the other hand the Lorentz forces applied to the charge carriers through the product crossing of the electric current with the magnetic field of the permanent magnets.
The acceleration stages consist of 4kV 2uF capacitors with a very small inductive impedance and a very small series resistance. These acceleration stages are activated sequentially thanks to the plasma that runs inside them.
The plasma has negative resistance, each discharge of the capacitor tens of thousands of amperes significantly increases the temperature and energy accumulated by the ions in addition to the speed.
What I want is that a plasma jet with great density, speed and temperature enters the hollow centripetal chamber.
The centripetation chamber must be made of alumina ceramic reinforced with stainless steel, the purpose of this chamber is to create a whirlpool of plasma that twists towards the center and compresses towards the center.
The energy of the ions must grow exponentially towards the center, since all the kinetic energy contributed by the consecutive discharge of the capacitors is compressed into an extremely small volume in the center surrounded by plasma that gets colder and colder the further away it is. in the center is the plasma.
The angular velocity of the plasma must be so high in the vicinity of the center that by means of the centrifugal effect the ions must be grouped together in a layer of the plasma, the electrons being of much less weight occupying a layer closer to the center, the constriction effect it must be able to overcome the electrostatic repulsive forces of the nuclei.
The only way out of the extremely overheated plasma would be perpendicular to the centripetal vortex and that is where we place an MHD generator.
I appreciate your attention and all the comments, thank you very much.
First you have to understand nature and then imitate it.
