The simulation code is able to calculate and predict changes in TAE instability to increase fast ion confinement and ensure the success of fusion reactions.
The TAE instability occurs in the course of interactions between fast ions and the perturbed magnetic fields surrounding them. As a result, fast ions disengage from the plasma core, hindering ion trapping.
In plasma particles, fast ions are much higher in kinetic energy than general ions and increase the temperature and performance of plasma necessary for nuclear fusion. Therefore, stable fast ion trapping is essential in maintaining a nuclear fusion reaction.
The team at the Korea Institute of Fusion Energy (KFE) was able to develop the code by using and improving upon the Gyro Kinetic Plasma Simulation Program (gKPSP) nuclear fusion simulation code, which was previously used for plasma transport analysis. The team added a feature to the code that allowed it to enable electromagnetic analysis...
