Fig. 2: Accumulated fraction of disruption predicted as a function of warning time on the J-TEXT tokamak.

From: Disruption prediction for future tokamaks using parameter-based transfer learning

Fig. 2

The vertical dashed line at 10 ms indicates tardy alarms. The model is able to predict 100% of disruptions in the test set on the J-TEXT tokamak with a warning time of 1 ms, 96.36% of disruptions with 10 ms. A warning time of 5 ms is enough for the Disruption Mitigation System (DMS) to take effect on the J-TEXT tokamak. To ensure the DMS will take effect (Massive Gas Injection (MGI) and future mitigation methods which would take a longer time), a warning time larger than 10 ms are considered effective.
