Another reactor family added to the collection

There is a collection of reactors that could generate ignition in different configurations

The last one is designed to try confination of 100% of the alpha particles to make a more useful and compact reactor without external energy harvesting coils, but a lot of new simulations will be done to see if it is possible. This is the result of simulation of the new SIX reactor

 

Simulated 5120 tokamaks configurations using aneutronic fusion

A 63 times improvement is reached from an initial configuration

The achievement was done using the step solver to go through 5200 simulations

In the following table appears the result of the simulations, where the X-axis is the simulation number and the Y-axis is the effective reactor area (in square meters):

In the following figure can be seen one of the 5200 simulations with 196 particles flowing inside the tokamak:

The real effective area must be much lower as it has seen in one of the simulations due the real plasma occupancy inside the torus is far to be  uniform as can be seen in the following figure:

Simulation of Tokamak devices

A solver is used over a simulator to simulate Tokamak devices to look for the possibility to use them in aneutronic fusions in the combustion chamber of the Miranda reactors.
In order to do that a giant magnetic field must be used to confine 550keV particles.
In order to simulate thousand configurations, it is used 4 threads over C++ with improvements like using elliptic integrals to increase the simulation speed
The reactor cross-section divided by collision probability is too high so a lot of simulations must be run to increase the performance.
It is improved the Aeff that is the averaged reactor section by using the “23 fellow system”, which involved to generate vectors of parameters with a variation between them using genetic algorithm but when having more than 23 vectors the worst of them is erased, then the percentage of variation is reduced every time a new vector is obtained as a variation of the 23 fellows.
After 10 kilosimulations of different Tokamaks structures with 4 to 12 toroidal coils are been simulated. Thanks to the 23 fellow system the performance is increased in very few simulations as can be seen in the yield table using logarithmic scales:

Simulation of the confinement chamber of the Miranda reactor

Accordingly simulations using the 4th simulator, version 3 and using the kinetics module designed for magnetic simulators #4 (version 14), it was stated that the containment of the fusion particles reaches almost 100% during the establishment of the magnetic field.


This could help because increase confirmation time over 100 microseconds would allow reaching ignition conditions without enhancement methods (that could be added after).


The data exposed in the excel table were calculated using a two coil system, where it was used the expected confination time. Here are the simulations for only 40 particles in one of the proposed configurations:

Particle Simulations of the Miranda reactor

It is simulated using a new kinetic simulator the Miranda reactor in configuration named 3N30x0945 using protons over 500 keV. It is stated a margin of the 35% over the energy range to confine the particles. The Larmor radius will be under 40% of the thin plasma chamber.

New magnetic simulations

We have released two new magnetic simulators

The first of them allows to calculate particle trajectories inside our reactors by using  multiwire simulation of thick coils with exact result needed in order to allow  compression of plasma using our EAC (Extreme Atomic plasma Compressors)

 

Also using elliptic integrals to have exact value of magnetic field it is designed a simulator subsystem that generate trayectories of particles to make kinetic diagnostic of accelerated plasma included speed and density over the 300 keV

 

The simulator will be used in the divertor design to eject particle debris after ignitions
