 Wednesday, March 15, 2023, 15:56, Albert Kong, Maintenance, Target 2, Controls, T2 - M9 and M20 beam blocker actuation and vacuum test 6x
|
We tested the actuation of the M9/M20 beam blockers on the T2 monolith (3-4pm).
Vacuum levels remained steady throughout so the M20 o-ring replacement that was performed this shutdown was successful (see strip of 1ACG4 - vacuum
gauge for T2 systems interlock). |

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, 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. |

Tuesday, October 17, 2023, 14:25, Albert Kong, Maintenance, Other, Other, T1/T2 Air Amplifier Spool O-Ring Servicing
|
Today we re-lubricated the o-rings on the top air amplifier for T1/T2, and replaced the o-rings on the bottom air amplifier with new and also lubricated
o-rings.
We used Haskel lubricant #50866. |

Thursday, January 11, 2024, 15:10, Albert Kong, Maintenance, Other, Cooling, T1/T2 Cooling Pkg. Proteus Paddle Wheel Maintenance, CUNO Filter Replacement, and Fitting Inspection
|
The following tasks were performed:
All electrical, water, and pneumatic connections to the T1 target was reconnected.
3x and 2x CUNO filters for T1 and T2
respectively were changed (O-ring for the housings were not changed).
All hansen fittings on the front mounting plates of the T1 and T2 cooling |
|
Thursday, February 15, 2024, 14:53, Albert Kong, Maintenance, Target 2, Air amplifiers, T2 Lower Air Amplifier Maintenance/Rebuild
|
The lower amplifier for the T2 target station air supply was removed for teardown, inspection, and rebuild.
The goal of this operation is to understand wear development in the air amplifier over ~13 years of operation, and potentially determine a recommeded
service interval. |

Friday, November 29, 2024, 11:57, Adam Newsome, Maintenance, Other, Hot Cell, Hot cell and warm cell maintenance tasks
|
The following maintenance tasks were completed on 2024-11-29 by A. Newsome, A. Kong, A. Tam, M. Dalla Valle:
Warm cell right window water level topup... the water level was a couple inches lower from the top. Using a tube connected to the nearby
sink, the level was topped up fully. See attached before/after picture.
Hot cell oil level checks:
Right side OK. |

Thursday, January 23, 2025, 16:58, Albert Kong, Maintenance, Other, Cooling, T1/T2 CUNO filter exchange, hansen fitting inspection, T2 FGSEC proteus electronics replaced, T2 FGSEC and Q1 paddle wheel replaced
|
All CUNO filters at T1 was exchanged on Jan 17.
At the time, access to the CUNO filters at T2 was obstructed by a shielding block, we will exchange these filters once the block is moved.
All Hansen fittings on the target station were inspected, all o-rings found to be in good condition. |
|
Thursday, January 23, 2025, 17:09, Albert Kong, Maintenance, Other, Cooling, T1 T2 water solenoid valves rubber gasket and o-ring exchange
|
All rubber components on the T1 T2 water solenoid valves were exchanged on Jan 22, 2025.
To service the heat exchange water and all collimator solenoid valves, the low active copper supply line in the 1A tunnel had to be shut off (see
pictures). Note that the shut off for the T2 secondary water did not work perfectly, it is possible that there either the valve was not shut off properly |

Friday, June 22, 2012, 13:48, Isaac Earle, Development, Target 1, Cooling, T1 & T2 Expansion Tank Level Sensor Recording Enabled
|
Mike Mouat enabled recording for T1 and T2 expansion tank warning and trip level sensors on XTPAGE/XSTRIP.
XSTRIP output is in discreet integers as follows:
2 = Both sensors OK |
|
Tuesday, July 17, 2012, 15:30, Isaac Earle, Development, Target 1, Cooling, T1 & T2 Expansion Tank Level Warnings Added
|
Mike Mouat and Juan Pon have modified the control system so that the control room will receive a message when the warning or trip level sensors
for the T1 & T2 expansion tanks read "NOT OK". The message also displays the current water height in the tank. This will help
with earlier detection of water leaks from the cooling package or from the target ladder in the vacuum volume when the vacuum interlock has been defeated. |
|
Monday, July 23, 2012, 16:01, Isaac Earle, Development, Target 1, Target, Target Flask Seismic Restraint Clamps Installed
|
Installation of the seismic restraint clamps has been completed for the MK1 and MK2 target flasks in the Remote Handling lab (photos attached).
Two clamps on the MK1 flask required 3/8" shims due to warpage of the flask baseplate (see photo IMG_0429).
Dragan Mitrovic has been notified so that he can inspect the installation and close the work request. |

Friday, April 12, 2013, 17:33, Isaac Earle, Development, Target 1, Cooling, T1 & T2 high-temp limit switch installation, wiring, and commissioning complete
|
Installation, wiring, and commissioning of the high temperature limit switches for the T1 and T2 cooling packages was completed today as part of SAS
project SASP0120. The relay output from the switches was wired in series with the Central Safety System signals for T1 and T2 (cable number 13250
and 12250 respectively) in break-out panel #2 on the Meson Hall south mezzanine. There were already 3 other circuits wired in series with each signal |
|
Friday, April 19, 2013, 09:55, Isaac Earle, Development, Target 1, Cooling, T1&T2 cooling package safety/standards compliance upgrade complete (SASP0120)
|
Yesterday (April 18th) the T1 and T2 cooling package PRV outlet lines were routed to the active drain in the 1A tunnel. All items for the safety
and standards compliance upgrade for T1 and T2 as specified in Document-68861 are
now complete. |
|
Tuesday, May 14, 2013, 13:26, Isaac Earle, Development, Target 1, Target, T1 & T2 Profile Scan
|
The T1 and T2 profile monitors were used during today's development shift. Target ladder movement for T1 was done at the panel on the mezzanine,
for T2 the portable control box was used. Both monitors actuated properly and the scans did not show any "missing" wires. The profiles
at both targets were found to be too broad and were adjusted to span 2 wires horizontally and 6-7 wires vertically (Yi-Nong Rao). |
|
Wednesday, October 23, 2013, 15:30, Isaac Earle, Development, Target 1, Cooling, T1 & T2 High Temp Safety Switch Tested
|
An end-to-end test was performed on the new T1 and T2 high temperature safety switches yesterday during the maintenance day. The switch set
points were lowered below the current temperature and it was confirmed that all warning messages and XTPAGE status changes occurred as expected. |
|
Tuesday, March 25, 2014, 18:24, Isaac Earle, Development, Target 2, Water Leak, Water Detecting Sensor Install at T1 & T2 9x
|
Water detecting strips were installed around the T1 and T2 areas today with Doug Preddy and contractors from SMT Research. Four sensors were installed
at various locations on each cooling package. Four sensors were installed on the top surface of the T2 monolith. In addition, four sensors
were routed for future installation at the T1 monolith (it is currently covered by blocks and requires cleaning and painting before sensor installation). |
