During commissioning in 2021, a short circuit in the poloidal field coils caused a lengthy investigation and repair, which was completed earlier this year. Although the JT-60SA is only using ...
It features a one-foot-long solenoid magnet with 12 toroidal field coils and eight poloidal field coils that help shape the plasma. Triangularity in a tokamak is the shape of the plasma in ...
How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...
