"Advancements in Tokamak Plasma Rotation and Transport Code"

Researchers from the Chinese Academy of Sciences have developed a new computational code, named TransROTA, for analyzing plasma rotation and transport in tokamak devices like the Experimental Advanced Superconducting Tokamak (EAST). The code enhances the prediction of ion velocities and the understanding of angular momentum balance in toroidally rotating tokamak plasmas, which is crucial for controlling instabilities and improving the performance of fusion experiments. The improved code is more resistant to numerical instability and is user-friendly, offering a valuable tool for theoretical and simulation research in fusion energy.
