2018 Cyclotron lid up problem. Station #9 was found to have the motor wires along the beam plain had damaged wire insulation. There were
bare wires in the conduit resulting in the wires shorting out. The wires were repaired with a quick short replacement. Lid went up for in tank work. After
lid down the problem was investigated. We checked the radiation levels at all of the stations to come up with a plan to determine witch of |

On Sep. 3rd during the 6 hr maintenance day, Doug Preddy
& I went into the 1A tunnel under “controlled access” to investigate a water leak that triggered the Water Detection Sensors. It was also noticed that the Cu-ALCW tank level was losing water. |

On 14Oct2014, the 1AT2 Collimator B water outlet temperature rose to 100o C.
Troubleshooting the T2 Collimator B water out temperature (T7) by swapping it's analog
signal in PIE box #2 with T2 Collimator A water out temperature (T6) to see if problem follows. See if unplugging T7 signal causes Safety Page SV7 1A Collimators |

Friday, October 02, 2015, 17:25, Ron Kuramoto, Standard Operation, Target 1, Target, Raise Target to lower Rad levels for 1AM7 repair
|
Today the T1MK2 target was moved from Position 4 to Position 0 to lower the Rad fields for the 1AM7 repair in the 1A Tunnel. The Rad levels were still
to high only dropping by 1000uSv/Hr to 5000uSv/Hr, so the 1AM7 repair is planned for next Tuesday's maintenance day on Oct 6th. 1A will be off till
then giving a longer cool down. |

Friday, April 09, 2021, 12:42, Matthew Gareau, Maintenance, Target 2, Cooling, Changed the paddle wheel, o ring, and shaft in the Collimator A flow meter at the T2 package
|
With the assistance of Maico we changed the paddle wheel, o ring, and shaft in the Collimator A flow meter (Q4) at the T2 package.
Flow meter was wiped clean to ensure o ring surface was clean.
Everything was changed without incident, and ops confirmed that the flow rate is now normal. |

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 |

The T1/T2 water packages were drained into the B1AAWHT (280L), the water was sampled and tested by RPG, results included in elog.
Once given the all clear myself and Maico released the water from the B1AAWHT (300L).
It was discovered that the solenoid valve SV1 which is located in the RH lab beside the sump, is broken and will need replacing, picture included |

Today myself and Adam Newsome started the leak detection steps for a target exchange and notice that the Helium line was not connected/broken from inside
the hotcell.
A new line will need to be installed and the line attached to the helium wand. |

Friday, September 23, 2022, 10:51, Matthew Gareau, Standard Operation, Target 2, Target, Target T2-MK2 moved to storage pit
|
The T2-MK2 target was transported from the east hot cell to the storage pit at position 3.
As was noted in the past, position 3 is difficult to align. The flask alignment pins prevent the flask from positioning in the correct location,
and it is required to have the flask just above the pins to ensure that the pins did not restrict the flask movement. |

The T2 heat exchanger secondary side solenoid failed on July 9 at approximately 19:30 (EPICS ID: B1A:T2CS:SVSEC). The valve was replaced with a
spare and the cooling package is now running normally.
The valve at this location also failed in November 2016: https://elog.triumf.ca/TIS/RH-Meson+Hall/211 |

Thursday, November 01, 2018, 13:57, Keith C Ng, Other, Other, Other, nuclear venillation in hot cells not working
|
Randomly checked on the nuclear ventilation for the Meson Hall Hotcells and discovered they were not running again (both magnahelic gauges displayed
zero). Attempted to restart the fan manually and the control box seems to not be working. Matt McClean has been contacted and they will look into the problem.
The nuclear ventilation is currently not running in the RHMH hot cells. |
