TM3 was moved into SMP Oct 25 morning. After two nights pumping down, SMP CG1 read 30mtorr this morning. The pump is stopped. SMP will be
vented soon for TM3 moving back to silo. |

Monday, October 28, 2019, 12:00, Isaac Earle, Safe Module Parking, Development, , , SMP shielding attenuation measured & compared to theoretical values
|
The attenuation of the SMP shielding was measured as part of SMP commissioning (Document-170404, R1, Section 4, Test #8)
The field on the shutter side of TM3 was measured without any shielding as it was removed from a storage silo. At 0.5m from the edge of the
module the maximum field was 5.00mSv. After installation into the SMP the maximum field outside the SMP shielding at 0.5m from the edge of the module |

|
The SMP main control panel and remote control module were updated in order to implement the following items which were deemed desirable during commissioning:
24 VDC line added to E-stop circuit: |

Thursday, October 31, 2019, 08:49, Anders Mjos, Conditioning Station, Repair, , , Water leak on non-active cooling water circuit
|
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 |

Thursday, October 31, 2019, 10:17, David Wang, Assembly/Bench Test, Maintenance, TM2, , Febiad target gas line leak check.
|
Feibiad gas line for ITE and its adapter fittings for TM2 are tested today by installing them on a dummy water stem. No leak on VCO fitting, adapter
o-rings, and all Swagelock fittings of this assembly. Manual valve on gas line works fine. The positional check on gas line between TM2 and ITW will
be fulfilled next Tuesday during module disconnection. |

Thursday, December 12, 2019, 14:39, Isaac Earle, Safe Module Parking, Development, , , SMP assembly shifted 1.0" north
|
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 |

Thursday, January 02, 2020, 09:55, David Wang, Cooling, Standard Operation, , , I turned on HALC water pump MP2.
|
HALCW MP2 is switched onnow. There is a small amount of air trapped in system. The pump works fine. Water level and system resistivity will be
monitored for a while.
LALCW P5 and P6 are switched on for cooling HALCW. HALCW MP2 is in operation now. |

Thursday, January 02, 2020, 10:10, David Wang, Crane, Standard Operation, , , TH crane issue.
|
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 |

|
The Target Hall Crane bridge and trolley motion was lost after a period of the crane having power disconnected over winter holidays. This is reported in
the following e-log: https://elog.triumf.ca/TIS/RH-ISAC/2039. This issue is a duplicate of what happened in 2019 at this time: https://elog.triumf.ca/TIS/RH-ISAC/1845

Tuesday, January 07, 2020, 08:02, David Wang, Cooling, Standard Operation, , , Switch on HALCW MP2
|
HALCW MP2 is switched on this morning after yesterday cooling tower maintenance. LALCW P5 and P6 pumps are started by isac operator as well. The
system is good so far. |

Wednesday, January 08, 2020, 10:34, David Wang, Assembly/Bench Test, Development, , , Module lifting assembly ITA0490
|
The second module lifting assembly ITA0490 is moved into TH and installed onto TM3 . It will stay with TM3. I adjusted the CofG on the assembly.
It is same to the first lifting assembly we are using now. After adjustment, The installation of assembly on TM3 are smooth. |

With both stations in operation,ITE dump supply gauge reading is 27 psi. ITW is 20 Psi. I adjusted ITW dump pressure to 25 psi by changing the
return line side pressure relieve valve.
ITE full operation+ ITW no TM: ITE dump pressure 27psi, ITW dump pressure 27psi. |
