1. A problem occurred during the FEBIAD HP Ta fin diffusion bonding and was discovered after the evaporator chamber was opened.
The washer was "wielded" on to the left leg of the target (see attachment #1: washer on target leg). |

According to Jonathan Aoki, the electricians will be servicing another MCC which will result in loss of cooling water for about 8 hours starting at 16:00
March 30. We shouldn't be running the evaporator or any condensers at that time. |
