A large (water?) leak opened up with target close to max temperature. Water lines were pressurized in an attempt to identify the leaky line. The test yesterday were not conclusive and was repeated this morning with no He response. The vacuum did not improve over night.

With the leak detector pumping on the left coil line, a large leak could be confirmed at the soldering site. |
