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
In order to sustain the reaction, it is needed to generate more energy than injected. one method is using created alpha particles to heat up the fuel. As long as >2.2MeV particles are very difficult to confine, only a few of them remain inside, so the confinement must be increased.
Here is a short simulation of one of the 145000 Tokamak-like simulated reactors:
This impressive video hides a real hard work to deal with extremely high speed and high accuracy simulation of thousand reactors, 24000 of them advise to reach ignition
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:
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:
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.
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
