Yesterday a leak was discovered in the ISAC-I experimental hall. The leak appears to be at the connection between the evaporator and the return water
line. 1 in of water was lost from TCS:TK1. The water is currently valved off to prevent further leakage.
A fault reportt has been submitted to mechanical |

|
The SMP assembly was shifted approximately 1.0" north today by pushing it, braced against the south wall, using a 100 Ton capacity air lifting bag
supplied by Beamlines Group. The move was one of the action items identified at the Gate 4A/4B close-out review. During commissioning of the
SMP, TM3 was installed into the vacuum vessel, which required the crane to be all the way at its south limit, so the move is to provide some margin for |

|
Target hall crane does not work properly after TH crane main power is switched off during Christmas time in control room. I switched the main power
back this morning. The only movement could be operated is crane rotation. Power is supplied crane. The control on N-S, E-W and up-down movements
do not work. We had the same problem last year. After trouble shooting, It was pointed to a PLC battery issue. Control group changed the battery and reloaded |

ITE bias test is done to 48KV. No spark. We can not raise bias above 48KV. It looks like we have a current limit issue on control system when testing
above 48KV. John Cow checked current limit on PS locally. It is set to 8mA which is much higher than the test current. Isac operator issued an e-fault
to control group. |
