Tuesday, May 09, 2017, 16:35, Isaac Earle, Repair, Target 2, Cooling, T2 target water flow gauge paddle wheel changed
|
During the target move on Thursday May 4th the paddle wheel and paddle wheel shaft for the T2CS:FGTGT sensor were changed to address transient
spikes of approximately +/-1.0 gpm which were causing nuisance trips. There have been no transient spikes recorded since the change, and the nominal
flow value dropped from 4.9gpm to 3.6gpm. Fault report #9836 has been returned, and the warning and trip levels, which were set higher to avoid nuisance |

Wednesday, April 17, 2013, 16:43, Isaac Earle, Standard Operation, Target 2, Target, T2 target installed; Vacuum leak-tight; Monitors OK; T2 ready for beam
|
The T2-MK2 target was transferred from the storage pit to the beam line yesterday (April 16th). The field was measured to be approximately 165mSv/hr
at 0.5m from the target ladder (after approximately 5 months of cool down time). Vacuum was started this morning and has pumped down normally (1ACG4
at 11mTorr after ~5 hours) indicating that the target is leak tight. |

Monday, May 15, 2017, 16:55, Isaac Earle, Other, Target 2, Target, T2 profile monitor actuation issue
|
On Thursday May 11th operators attempted to move the T2 profile monitor (T2-MK2) to the IN position but were unsuccessful. The monitor would
leave the OUT limit, but would not reach the IN limit. This was repeated 2 times. The air amplifier was inspected and nothing out of the ordinary
was noted. The T1 profile monitor was tested and was working properly. At the time it was suspected that the monitor cassette had become dislodged |

The following maintenance tasks were performed during mini-shutdown of 2022 with the goal of resolving the Fault 14966 (target water flow rate low).
Replace the o-ring, paddle wheel, and shaft on the following flow rate sensors:
Q1 (FGTGT)
Q2

Wednesday, April 05, 2017, 17:55, Isaac Earle, Development, Other, Target, T2 area devices alignment strategy
|
A strategy for alignment of the T2 protect monitor, T2 target, and T2 Collimator A was discussed today and decided upon by Yuri Bylinski, Isaac Earle,
Yi-Nong Rao, and Roman Ruegg. The purpose of the adjustment is to try to reduce the amount of beam lost as it passes through the T2 area (presumably
being blocked by the collimator because it is not possible to steer the beam through all three devices in their current configuration). Keeping in |

Thursday, June 21, 2012, 13:38, Isaac Earle, Standard Operation, Target 2, Cooling, T2 Water Package Started
|
The T2 water package was reconnected to the target and started after being shut-off since April 12, 2012. The M9 and M20 groups do not anticipate
having to vent the T2 volume, so the package will be left running in preparation for BL1A start-up in early July. There was no change in T2 vacuum
levels during start-up, and therefore no water leaks into the vacuum volume. |

Monday, May 28, 2012, 17:17, Isaac Earle, Repair, Target 2, Cooling, T2 Water Loss Update
|
The T2 cooling package, the top of the T2 monolith, and the Hansen water connections which connect the package to the target were inspected and
no evidence of a water leak was found. Kim wipes had been stuffed inside the female Hansen fittings after they were disconnected on April 12th, and
these were also completely dry. I checked with control room and there are no log entries regarding anyone starting the cooling package during the |

Friday, November 22, 2013, 20:26, Grant Minor, Repair, Target 2, Water Leak, T2 Water Leak - Target Assembly Removed and Water Sucked Out of B/L

T2 target water leak was identified earlier this morning.
Isaac Earle, Ron Kuramoto and Keith Ng co-ordinated Meson Hall blocks removal and target flask transport.
Target assembly was removed from B/L approximately 5pm. |

Wednesday, April 11, 2012, 17:02, Isaac Earle, Repair, Target 2, Target, T2 Vacuum Interlock & Expansion Tank Level Sensor
|
The problem with the T2 vacuum interlock was fixed by restarting the "Crate TG1" control panel microprocessor. The T1 and T2 vacuum
interlocks were retested several times and are functioning properly. Fault report #5907 was returned.

Tuesday, March 31, 2015, 17:40, Isaac Earle, Repair, Target 2, Cooling, T2 Thermistors Replaced
|
The Inlet (T1), Outlet (T2), Col.A (T6), and Col. B (T7) thermistors at the T2 cooling package all gave intermittent faulty readings at various times
between Oct - Dec 2014. It is suspected that this was caused by a water leak in the area causing the terminals to get wet. Inspection of the
sensors revealed that they are in poor shape and that the readouts sometimes fluctuate when the probe or connectors are handled. All four thermistor |

|
In preparation for extended periods of the T2 volume being vented during the M20 repair, the T2 water package was shut-off, the water lines were
disconnected from the target, and the cooling water was removed from the target using compressed air. |

Tuesday, June 03, 2014, 22:56, Isaac Earle, Standard Operation, Target 2, Target, T2 Target Position Moves (Development Shift)
|
The T2 target was moved from Position 4 to Position 0 at 11:15am so the profile monitor could be used during the development shift.
The T2 cooling package tripped regularly throughout the day on high flow while in position 0.
At 10:45pm the T2 target was returned to the previous running position: approximately 2mm above the nominal position 4 elevation (pot ratio fluctuating |

Thursday, February 13, 2014, 14:27, Isaac Earle, Standard Operation, Target 2, Target, T2 Target Moves

The T2-MK1 target was moved from the beam line to the target storage pit in position 4. The target was measured to be 30mSv/hr at 0.5m. The
move went smoothly.
The T2-MK2 target was then moved from the hot cell to the beam line. The target was 151mSv/hr at 0.5m. For reasons unknown the target |

|
The T2-MK2 target (currently installed in the beamline) was moved from position 0 to position 4 (10cm Be) using the portable control box.
The T2 cooling package was started after moving the ladder.
There was no change in the BL1A vacuum. The T2 expansion tank water level dropped slightly, as expected (around 1/16"), and was refilled |

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. |

See Cyclotron fault 16553.
"B1A:T2CS:FGTGT readback is toggling at the warn limit of 3.0 GPM and over the last week has started crossing over the trip threshold of 2.8
GPM, tripping off the water package. Initial Action Taken: 1A is scheduled to take beam on December 13." |

Monday, January 15, 2024, 16:36, Albert Kong, Standard Operation, Target 2, Cooling, T2 Resin Flask Exchange
|
The resin flask on the T2 cooling package was exchanged today (new resin can prepped in the morning).
The newly installed resin flask was placed slightly off-set from the marking on the platform to ensure that the braided hose will clear the blocks
when replaced at the end of shutdown. |

Monday, May 05, 2014, 15:46, Isaac Earle, Repair, Target 2, Target, T2 Protect Returned to B/L
|
The T2 protect monitor was returned to the beam line using the shielded flask. The alignment pin did not align with the hole in the vacuum flange,
but could be aligned by hand by rotating the monitor assembly while it was hanging from the flange. The protect monitor vacuum flange was bolted
down and all services connected. The T2 protect and profile monitors were checked by Dave Cameron (both OK). Vacuum was pumped down and the |
