I am sorry to say this, but it looks to me like Jiang had the same problem this time as last time. The T2 thermocouple in the center of the cell overheated. It exceeded the 1372°C limit for that device. It probably did this early in the experiment on May 4. After that it is erratic, and I do not trust the readings. Thermocouple T2 on the outside of the cell does not show self-sustaining anomalous heat after power is turned off. It falls smoothly and monotonically.
At the end it says "T2 destroyed." I suspect it was destroyed earlier. This is shown in Fig. 2. The configuration is in Fig. 1. - Jed
