 Monday, January 18, 2016, 17:19, Isaac Earle, Standard Operation, Target 1, Cooling, T1 & T2 Packages Drained; BL1A Holding Tank Released
|
The T1 and T2 cooling packages were drained to the BL1A holding tank on Jan 8 2016. The volumes were 100L and 80L respectively. Before
starting there was 350L of water in the holding tank from the 500MeV system which Steve Sapriken drained in September 2015. The T1 and T2 systems
were sampled and delivered to RPG. After receiving permission from RPG to release all 3 portions of water it was pumped into the city sewer on Jan |

Monday, January 12, 2015, 16:35, Isaac Earle, Standard Operation, Target 1, Cooling, T1 & T2 MRO Status
|
The following tasks have been performed at T1:
- T1 monolith painted using grey two part epoxy paint
- Video inspection taken while package running. Small leak from both valves on H.E. secondary side (video on Isaac's PC, too large to upload) |
|
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. |

Thursday, February 09, 2012, 17:19, Isaac Earle, Repair, Target 1, Cooling, T1 & T2 General MRO
|
The following work was performed on the T1 cooling package:
- New filter housing installed for Col. A filter. The new housing has a drain valve to prevent water spills during future filter changes.
- Ball valve installed upstream of Col. A filter to allow proper isolation of filter during filter changes. |

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. |
|
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 |
|
Wednesday, July 15, 2015, 10:33, Isaac Earle, Standard Operation, Target 1, Cooling, T1 & T2 Cooling System Check
|
- All T1 and T2 values on XTPAGE were stripped back to April 1, 2015: All systems appear to be functioning normally, nothing unusual observed
- Expansion tank levels checked visually: T1 level at 1/2" above top sensor nut, T2 level at 1/4" below top sensor nut --> filled
to 1/2" above |

Thursday, February 06, 2014, 17:05, Isaac Earle, Standard Operation, Target 1, Cooling, T1 & T2 Cooling Package Filters Changed
|
Water was drained from the T1 and T2 cooling packages, samples taken, and delivered to RPG.
All filters on the T1 and T2 cooling packages were changed except for the T1 demin. line filter which is hard to access and could not be properly
drained. This filter will be changed next shutdown when the area is more accessible while the resin cans are being changed. |
Thursday, March 31, 2016, 11:48, Isaac Earle, Standard Operation, Target 1, Target, T1 & T2 Beryllium Target Manufacturing Complete 
|
Manufacturing of a new batch of T1 and T2 beryllium targets has been completed.
The job was completed under Machine Shop Work Order #41527. Eleven 12mm T1 targets (TBP1683) and seven 10cm T2 targets (TBP1691) were completed
(exhausting all stock of the leftover EDM'd target housings). The target window profiles (TBP1695) were laser cut at an outside shop for greater |

Thursday, January 05, 2012, 10:18, Isaac Earle, Maintenance, Target 2, Cooling, Swapped Resin in T2 Cooling Package
|
Drained T2 cooling package water, collected sample and delivered to RPG. Swapped resin can, refilled, and restarted cooling package.
After 6 hours can inlet at 10.3MΩ *cm,
can outlet at 10.5MΩ*cm electrical resistivity. |

Wednesday, January 15, 2014, 15:38, Isaac Earle, Standard Operation, Target 2, Water Leak, Suck Tube Drained and Rinsed
|
The suck tube vessel was drained, rinsed, and transported to the active sink area in the Meson Hall Hot Cell Lab. There are no longer high fields
from the suck tube and it is ready for future use. The filter, tubing, and flange used for filtering the active water were removed and bagged and
are currently stored in the south-east corner of the warm cell. This bag measured up to 12mSv/hr on contact. There are small black particles |

Thursday, February 01, 2024, 11:16, Albert Kong, Standard Operation, Other, Cooling, Spent resin can rinse, purge, and drying
|
The recently removed resin can from the T2 target station was rinsed with city water and flushed with compressed air for 1 cycle.
We will run it through a few more cycles before proceeding with drying under the fume extractor, at which point this ELOG will be updated.
UPDATE (Feb 08, 2024): The T2 resin can underwent 3 more air cycles. Today it was moved under the fume extractor with the lid cracked open and |

Tuesday, December 20, 2011, 09:54, Isaac Earle, Maintenance, Target 1, Target, Replaced T1-MK1 Target Ladder
|
Replaced T1-MK1 target ladder with the new ladder design which has an integrated upper slide plate (2 less sealing locations) and no c-seal grooves.
C-seals replaced with aliuminum delta seals.Transfered all target cassettes to new ladder in the same positions. Performed helium leak check
at interface with bellows flanges and all cassette locations. No leaks detected. |

Thursday, January 12, 2012, 11:34, Isaac Earle, Maintenance, Target 2, Target, Replaced M20 Beam Blocker Vacuum Seal O-Rings
|
Replaced M20 beam blocker vacuum seal o-rings. Old o-rings were noticeably harder, but not brittle or cracked. Applied "Haskel
Dry Air Seal" lubricant to air cylinder shafts and "Apiezon M Grease" to vacuum seal o-rings and main shaft. Took approximately 1
full days work. Total dose: 0.08mSv. |
