 Wednesday, January 10, 2018, 17:45, Isaac Earle, Standard Operation, Target 2, Target, T2-MK2 beam spot photos, M20BB moved to storage pit 
|
The T2-MK2 target was moved from the beamline to the hot cell on January 8th. The field at 0.5m was 130mSv/hr. Photographs of the beam
spot of the Position 4 target are attached below. This is a 12mm beryllium target (ID: "JUL.06#4). This is the only target on the T2 ladder
that has seen beam since it was installed on October 10, 2017. A shielding plug was installed on the T2 flange. A new 5cm target will be installed |

|
The following is a summary of MRO work done on the T2-MK2 target during the 2018 shutdown:
Jan 8: |
|
Thursday, May 10, 2018, 15:23, Isaac Earle, Repair, Target 1, Target, T1-MK2 protect monitor and profile monitor replaced
|
During first injection of beam down 1A problems were encountered with the T1 protect monitor. Testing was done by Probes Group from the mezzanine
leading to the following investigation and repair work.
|
|
Wednesday, May 22, 2019, 14:25, Isaac Earle, Repair, Target 1, Target, T1-MK2 target moved to HC; T1-MK1 target moved to BL
|
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). |
|
Monday, June 24, 2019, 14:29, Isaac Earle, Development, Target 1, Target, T1 and T2 target alignment frames overhauled 8x
|
The following work was completed on both the T1 and T2 target alignment frames
One of the short taper pins on the top of the frame was swapped for a longer version to simplify flask alignment to the frame (now one
pin can be aligned at a time instead of both concurrently)
Three permanently mounted cameras installed to view east/west alignment, north/south |
|
Thursday, January 30, 2020, 17:55, Isaac Earle, Repair, Target 1, Target, T1-MK2 target assembly repair completed in hot cell
|
The following work was done to the T1-MK2 target in the hotcell between the dates of May 24, 2019 - Jan 30, 2020 (See E-Log #251 for further information):
May 24: Flushed position 2 with water, purged all positions with air. Left air running through position 0 over the weekend
May 27: Switched to position 5, left air running to dry out bellows
May 28: Started pump out with cold-trap; Reached "fine |

Tuesday, November 24, 2020, 15:10, Isaac Earle, Standard Operation, Target 2, Target, Additional targets added to T2-MK1 ladder
|
The following work on the T2-MK1 target was completed sporadically over the last few months:
Sept 22: |
|
Wednesday, March 31, 2021, 16:15, Matthew Gareau, Standard Operation, Target 1, Target, T1-MK1 target exchange
|
March 29 Monday
- moved T1-MK1 target from beamline to hotcell (field from target 15mSv/hr @ 0.5m)
- flushed water through position 4 |
|
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 |
|
Wednesday, April 13, 2022, 12:31, Adam Newsome, Standard Operation, Target 2, Target, T2-MK2 moved: from target station to storage
|
The T2-MK2 target was moved from the target station to the storage area (position 3). Upon removal, it was measured with a pole monitor at 0.5 m to be
960 mSv/h. |
|
Wednesday, April 13, 2022, 12:33, Adam Newsome, Standard Operation, Target 2, Target, T2-MK1 moved: from storage area to target station
|
The T2-MK1 target was moved from the storage area (formerly position 4) to the target station. Services were reconnected in order to prepare for normal
operation. |
|
Thursday, May 05, 2022, 14:39, Adam Newsome, Standard Operation, Target 1, Target, T1-MK1 and T2-MK1 profile monitor actuation test
|
The profile monitor actuation tests were completed for T1 and T2. No abnormalities were noticed in vacuum during either test.
Note: an issue was observed with T2-MK1 - see e-log 290. The issue was resolved. |
|
Wednesday, May 25, 2022, 10:15, Adam Newsome, Standard Operation, Target 1, Target, T1-MK2 moved from hot cell to storage area
|
The T1-MK2 target was moved from the hot cell to the storage area, in position 5. Note: manual nudging of the flask was required to get it to align with
guide pins properly. |
|
Wednesday, May 25, 2022, 10:16, Adam Newsome, Standard Operation, Target 2, Target, T2-MK2 moved: from storage location to hot cell
|
| Target T2-MK2 was moved from the storage location (formerly position 3) to the hot cell in preparation for replacement of end of life targets. |
|
Thursday, September 15, 2022, 14:34, Adam Newsome, Standard Operation, Target 2, Target, T2-MK2 target elevations measurement
|
The target elevations measurement and beam spot checks were completed on Sept. 15, 2022. This was done after a July 2022 target exchange for target positions
3 and 5.
|
|
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. |
|
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. |
|
Thursday, March 30, 2023, 13:17, Albert Kong, Maintenance, Other, Target, Air Amplifier Testing: M9 BB (AKA T2 blocker), M20 BB, T2 MK1 prof. monitor, T1 MK1 prof. monitor actuation
|
We tested the air amplifiers by actuating the beam blockers and profile monitors on the T1 and T2 target stations.
The blockers and profile monitors were each actuated (brought up/out and down/in fully) > 5 times and vacuum remained stable throughout (see
attached). |
|
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 |

Wednesday, January 10, 2024, 12:47, Albert Kong, Standard Operation, Target 1, Target, T1 target ladder exchange (T1-MK1 to hot cell roof, T1-MK2 from pit to station)
|
T1-MK1 was moved from the target station to the hot cell roof.
Radiation surveys report 140 mSv/hr at 0.5m for the bare T1-MK1 target ladder.
On the hot cell roof, fields are 220uSv/h at 0.5m. |
