Development of a Virtual Tokamak platform

We develop a virtual tokamak platform choosing KSTAR tokamak as the target device. The Unity® game engine is employed to visualize the KSTAR main device. It is shown that with a proper reduction of the CAD data, a fast and interactive display of the device can be achieved in personal computer. We also develop a data processing framework underlying the platform, which can deal with various data from tokamak experiment and simulation. Three plasma simulations are selected and integrated into the virtual platform: Monte-Carlo simulation of neutral beam injection (NBI), ray tracing simulation of electron cyclotron resonance heating (ECRH), and 3 dimensional resonant magnetic field perturbation simulation. We demonstrate that the platform can be used as a tool for monitoring and analyzing fusion experiment in virtual environment.
