About the Lab
Professor Gyungjin Choi's research lab focuses on advancing magnetic fusion energy through the development of high-performance, steady-state plasma regimes in tokamak devices. The lab specializes in understanding and optimizing plasma confinement, particularly through the innovative Fast Ion Regulated Enhancement (FIRE) mode, which leverages fast ions to stabilize core turbulence and sustain high ion temperatures over extended durations. Their work emphasizes advanced diagnostics, neutral beam injection, and the control of internal transport barriers to enable next-generation fusion reactor concepts. The lab's research contributes significantly to the realization of practical fusion energy by improving plasma stability and performance without reliance on complex profile control or excessive impurity accumulation.

1Abstract We report on the status of Fast Ion Regulated Enhancement (FIRE) mode experiments in the Korea Superconducting Tokamak Advanced Research. This regime is being developed for high-performance, steady-state operation which features a stationary ion internal transport barrier, enabling a central ion temperature approaching 10 keV to be sustained for up to 50 s, without the need for delicate profile control and with no significant impurity accumulation. As its key novelty lies in the signifi
