Abstract :
For the safe operation of Experimental Advanced Superconducting Tokamak (EAST) with higher plasma performance discharge in future, it is important to estimate the operation state of Toroidal Field (TF) magnet. The outlet temperature rise of TF coils and TF cases measured in experiment is analyzed. It is found that the outlet temperature rise of TF coils and TF cases increases with plasma current. The outlet temperature rise of TF coils and TF cases induced by plasma disruption is a small value, about 0.01 K. In addition, the outlet temperature rise of TF coils is not related to the plasma duration, but the outlet temperature rise of TF cases seems to increase with plasma duration.
