|
Replacement of the power supply fans for the T1 Power Supply, T2 Power Supply, as well as an additional power supply in rack 1A was completed this
morning. The boxes were blown out with air to remove dirt and dust. The inside of all boxes were inspected and no evidence of melting or burning
was found. |

|
The following work was completed between Jan 16 - Feb 19, 2019:
T1 and T2 cooling packages drained to South TNF holding tank, water sampled and tested, released after approval from RPG
T1
resin can swapped
All Cuno filters changed at T1 (3 total)
T1 inlet (T1CSPGIN) and outlet (T1CSPGOUT) pressure gauges replaced |
|
Wednesday, April 22, 2015, 15:15, Isaac Earle, Standard Operation, Target 1, Cooling, T1 and T2 Cooling Packages Ready
|
Both cooling packages are running steadily with the targets in Position 0.
The demin flow (Q2) for both was tuned to approximately 1.5USgpm.
A defeat was applied to T2Q1 flow to prevent high level nuisance trips. This will remain in effect for the 2015 running period. |
Thursday, January 12, 2023, 10:36, Adam Newsome, Maintenance, Target 1, Water Leak, T1 and T2 - Cooling Package Water Leaks - Ball Valves 
|
Upon uncovering the T1 and T2 areas to prepare for regular cooling package maintenance, it was discovered that multiple ball valves were leaking. Primarily
the Swagelok SS-45S12 parts, but some SS-45S8 parts have failed as well. There were small puddles of water underneath many of the valves. It appears that
the leak is due to a compromised seal. It is suspected that these parts failed from radiation exposure. They have PTFE packing material which is highly |

Monday, January 16, 2023, 09:54, Adam Newsome, Standard Operation, Other, Cooling, T1 and T2 - Cooling Package Drained
|
On Jan. 13, the T1 and T2 cooling package water reservoirs were drained to the BL1A holding tank. Water samples were obtained for each system and provided
to RPG for analysis.
Prior to starting draining, the BL1A holding tank water level was approximately 330L. After draining, the water level was approximately 550L (checked |

Wednesday, July 11, 2012, 17:51, Isaac Earle, Repair, Target 1, Target, T1 Target Swap
|
BL1A was started yesterday and brought up to 10μA. A problem was noticed with the T1 protect monitor (the right and bottom plates were not showing any response when the beam was swept
across the monitor). The protect monitor is new and was installed on the target assembly in February 2012, so this is the first time it has seen |
|
Friday, March 23, 2012, 14:50, Isaac Earle, Repair, Target 1, Target, T1 Target Leak - Update
|
The T1-MK2 target was transferred from the beam line to the hot cell. Water was seen in the bottom of the target pipe confirming that the leak
is from the target. The lower cone of the target assembly was submerged in the water and came up dripping wet. The profile monitor, protect
monitor, and two of the target cassettes were also wet. As it is not possible for those to be submerged, water was likely spraying from either the |

Tuesday, April 09, 2013, 17:06, Isaac Earle, Repair, Target 1, Target, T1 Target Electronics Check
|
The T1-MK1 target protect and profile monitor electronics were 'blip' tested by Bill Rawnsley on April 5, 2013. The response from the profile monitor
appeared normal, however the protect monitor response was very weak. After various debugging it was found that the 9 pin connector on the target
on the vacuum side of the vacuum flange had become disconnected from the vacuum flange feed-through. It is suspected that this happened while changing |

Friday, February 27, 2015, 18:06, Isaac Earle, Development, Target 1, Target, T1 Rotary Collimator Water and Air Line Investigation
|
Ron Kuramoto, Keith Ng, John McKinnon, and myself spent some time today investigating water and air lines related to the T1 Rotary Collimator (Col.
A). We discovered the following:
- There is a panel on the back (south) side of the T1 cooling package with 3 air lines for Col. A actuation, Col A cooling water supply & return, |

Wednesday, March 21, 2012, 17:28, Isaac Earle, Repair, Target 1, Cooling, T1 Package Water Leak - Update
|
The water level in the T1 cooling package expansion tank was checked again today approximately 24 hours after it was refilled. The level
had dropped about 5cm, equating to roughly 3.5L of water lost.
The T1 package was inspected thoroughly and no water was found. A leak on the target in the beamline is suspected. The T1 package has |

Thursday, March 22, 2012, 13:58, Isaac Earle, Repair, Target 1, Cooling, T1 Package Water Leak - Update
|
Vacuum group pumped down on the T1 & T2 volumes (because there is no cold trap on the T1 pump) for approximately 1 hour this morning. A
significant amount of water was found in the base of the cold trap which confirms our suspicions of a water leak on the T1 target.
Tomorrow we will transfer the T1 target from the beam line to the hot cell for inspection, leak checking, and repair. |

Monday, September 09, 2013, 16:22, Isaac Earle, Repair, Target 1, Cooling, T1 P1 Transducer Replaced
|
The BL1A tunnel was accessed today to assess a faulty reading from the T1 cooling package inlet pressure transducer (T1P1). The line was
first bled to remove gas bubbles which did not change the reading. The transducer was replaced with a new unit (OMEGA PX315-100GI). The pressure
reading returned to the usual value of approximately 74psi (faulty reading had been steadily decreasing over the last few months and was at approximately |

Thursday, April 06, 2023, 13:35, Albert Kong, Maintenance, Target 1, Controls, T1 Motor Controller Hearbeat Trip (+T2 Heartbeat Trip)
|
The T1 motor controller hearbeat tripped (noticed this morning).
This does not seem prevent beam delivery or target ladder actuation (see screenshot, target still ready for beam).
An improperly functioning hearbeat led on a controller may indicate that the controller is beginning to fail. |

Thursday, January 19, 2017, 08:55, Isaac Earle, Standard Operation, Target 1, Cooling, T1 MRO work complete
|
The following work was completed on the T1 cooling package:
- water drained to BL1A holding tank
- all resevoir o-rings changed |
|
Monday, January 25, 2016, 16:54, Isaac Earle, Maintenance, Target 1, Cooling, T1 MRO Work
|
The following work was performed at the T1 cooling package and target between January 18-21, 2016:
- Cuno water filters removed (3), and new filters installed
- Target water solenoid, H.E. secondary side solenoid, and Collimator A solenoids removed and replaced with new 24V DC versions |

Thursday, February 17, 2022, 13:03, Matthew Gareau, Maintenance, Target 1, Target, T1 MK2 wire scanner and protect monitor test removal and reattachment with pin straightening
|
this Work was done on 09 Dec 2021.
Since Isaac Earle was leaving Triumf he was giving us (maico, chad, adam, and myself) a demonstration of how to remove targets, protect monitor,
and wire scanner. During the removal it was noticed that one of the pins for the wire scanner was bent and it would not be possible to reattach without |

Tuesday, April 03, 2012, 15:55, Isaac Earle, Maintenance, Target 1, Target, T1 Ladder Position Look-up Tables Updated
|
| Graham Waters has activated the appropriate target ladder position look-up tables for the T1-MK1 target which was installed in the beam line yesterday. |

Tuesday, June 06, 2023, 15:42, Albert Kong, Standard Operation, Target 1, Cooling, T1 Heat Exchanger Low Flow Diagnostics
|
On May 31, the low active water in BL1A was turned off briefly and upon re-starting, the flow to the T1 heat exchanger was very close to the reported
warn limit (~6 gpm).

Monday, March 27, 2017, 16:15, Isaac Earle, Repair, Target 1, Cooling, T1 Cooling System Target Water Return Hose Damaged
|
The 18' shielding block which lies west of the T1 cooling package was removed on Friday Mar 24 so that vacuum equipment could be craned into the 1A tunnel.
During replacement, the flexible SS hose for T1 target return water got caught under the block and was ripped apart. Workers in the area did
not realize this had occurred. The cooling package tripped off when the hose ripped (likely due to low water flow or low supply pressure). In |

Friday, September 30, 2016, 16:59, Isaac Earle, Repair, Target 1, Cooling, T1 Cooling System Inlet Pressure Transducer Replaced
|
The T1 cooling system inlet pressure transducer (EPICS ID: B1A:T1CS:PGIN, Omega part # PX315-100GI) began failing in August (exhibited gradual
decline in pressure with no corresponding change to flow rate or outlet pressure). A new transducer was installed on Sept 30 2016 which fixed the
problem. Cyclotron Fault Report #9238 was returned and the temporary bypass on the warning level was removed. |
