After extensive testing over the last 2 weeks it was determined that the protect monitor
on the T1-MK2 target had an issue with intermittent shorting between the high voltage line and ground (movement of the target ladder was causing the short
to come and go). |

|
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. |

Wednesday, January 11, 2023, 15:22, Adam Newsome, Repair, Target 2, Target, T2 Target Ladder Motor - Coupling Failure
|
It was reported on Dec. 20, 2022 that when Operations attempted to run the target ladder motor, it was unresponsive. A fault report was created: 15477.
During winter shutdown 2023, the T2 area was uncovered and the motor was inspected on 2023-01-11 by Adam Newsome and Maico Dalla Valle. The connectors
and cabling appeared OK. |

Monday, January 16, 2023, 15:06, Adam Newsome, Repair, Other, Active Sump, RH Active Sump - draining flow rate sensor repair
|
The flow rate sensor used to monitor the drain rate from BL1A holding tank to active sump, located in the active sump area, was repaired. The paddle
wheel, o-ring, and shaft were replaced. This part was significantly worn prior to replacement.

Tuesday, January 17, 2023, 13:49, Adam Newsome, Repair, Other, Active Sump, Active Sump - Valve V6 Leaking
|
It was noticed today (2023-01-17) that the valve V6, used in draining the BL1A Holding Tank to the Active Sump, was leaky. This valve should be replaced
as soon as possible. It has been added to the MS
Planner maintenance tasks list. |

Friday, February 17, 2023, 14:36, Albert Kong, Repair, Other, Water Leak, T1/T2 Water Cooling Package Ball Valve Replacement
|
5 and 3 Swagelok ball valves were replaced from the T1 and T2 cooling packages respectively.
These are compression fit valves, 1/2" or 3/4" size.
1 valve in T2 was replaced previously, bringing the total # of replaced valves in T2 to 4. |

Monday, March 06, 2023, 16:58, Albert Kong, Repair, Target 2, Cooling, M20 O-Ring Replacement and Valve Replacement Leak Check
|
We replaced tha O-ring on M20 at T2 and brought the target station down to vacuum, which allowed the target water pump to be turned on.
After turning the pump on, we inspected the replaced valves for any leaks and found none - the flow on the demineralizing line was adjusted to
1.2GPM (also done at T1) by turning the needle valve. |

Thursday, May 11, 2023, 11:28, Adam Newsome, Repair, Target 1, Target, T1-MK1 - broken target ladder motor coupler repaired
|
See Cyclotron Fault 15787. The target ladder motor failed to move to the commanded position during a test. The T1 area was uncovered and the motor assembly
was inspected by M. Dalla Valle, A. Newsome, and A. Kong. It was determined that the rubber coupler which connects the motor shaft to the drive assembly
had degraded and snapped. This is similar to an incident which recently occurred on T2. The coupler was replaced with an all-metal version. The system |

|
The water level in the T2 cooling system expansion tank dropped to below the trip treshold of 20 cm (ref Cyclotron fault #16123), requiring the beam
to be 'defined' off (see attached image).
Some calculations (see attached .html) show that over the period in which the tank level was dropping (from July 12 - Aug03, 2023) approximatley |
