|
ITW secondary vacuum was bad in last two days after TM4 was connected in ITW. Today when check the exit 2 module, I found a small needle valve on exit
2 module top was slightly opened for some reason in past months. The valve is closed . ITW vacuum is returned to normal status. |

Monday, September 30, 2019, 11:27, Isaac Earle, Safe Module Parking, Development, , , SMP vacuum vessel modifications completed
|
The SMP vacuum vessel welds were reinforced to match the specifications on IRH1710 Rev D. In addition a tube stub was added on the side of the
vessel for installation of a PRV. The relief valve installed was Accu-Glass 113150, with 2psi setpoint (not the MDC 420036 model specified on IRH1710
Rev D). The drawing will be updated to reflect this. |

Friday, October 04, 2019, 16:50, David Wang, South Hot-Cell, Standard Operation, TM4, , UCx 28 target with TM4 SHC leak check and electrical check.
|
TM4 HS Leak check result is good . No leak. electrical check after target installation: Bias to chassis 550 Mohm. Coils are shorted each other and shorted
to 60 KV bias. ABCD to 60KV bias 500V Megga measurement are 100M at least which is good. EE to bias are OL at 500V. The electrical check result is good.

|
An update was made for the E-stop and power supply system in the SMP main panel. Upon testing remote control, it was determined that the Opto 22 AC module
was not sufficiently rated to handle the current draw of the motor (5A fuse versus motor 5.7A current draw). The design was modified so that the E-stop
chain, which supplies 120 VAC line voltage through the main panel E-stop then the remote module (or local pendant when plugged in), will now activate a |

Tuesday, October 15, 2019, 16:42, Isaac Earle, Safe Module Parking, Development, , , SMP flange alignment tested using shield plug
|
As a preliminary test in preparation for SMP commissioning, one of the steel module shield plugs was installed into the SMP to check the positional
and rotational alignment procedures. The following is a summary of the steps performed:
Shield plug lifted with crane and rotated to an arbitrary (non-orthogonal) position
Using the crane pendant the shield |

Tuesday, October 22, 2019, 16:26, Isaac Earle, Safe Module Parking, Development, , , SMP shield box grounding
|
A braided grounding strap was attached to the aluminum gear box support on the SMP shield box structure, and grounded by attaching it to the exterior
of an electrical conduit located in the south-west corner of the B2 area at the top of the silo in that corner. The braiding was also connected to
the stainless steel support structure for the SMP vacuum pump. |

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 |

|
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 |

|
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. |

|
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
