Hello Gerard,

We are having some cooling issues with PPB on the FST. 

The temperature of the PPBs was higher than last run and triggered the alarm. Then we found that part of the supply/return loops for the cooling water (far away from the center of the pole tip) was not connected. So we connected them and indeed the temperature went back normal, but leakage was found in one out of the 3 lines. It will be hard to track down the leak, even worse to repair it, so we are thinking whether we can raise the temperature limit of PPB and how much we can raise it.

Regards,

Ziyue
