 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. |

Tuesday, July 03, 2012, 13:23, Isaac Earle, Standard Operation, Target 2, Target, T2 Plug Block Replaced & Beam Blockers Tested
|
The T2 plug block was replaced and the M9 and M20 beam blockers were tested. The plug block did not interfere with the travel of the beam blockers.
There was no change in the T2 vacuum during BB actuation.
Initially there was some confusion about how to actuate the beam blockers. The following was learned: |

Monday, July 09, 2012, 17:17, Isaac Earle, Standard Operation, Target 1, Target, BL1A Start-Up Prep
|
- T1 & T2 targets switched to "remote" control
- Both target ladders were moved to Position 3 (12mm Be)
- T2 Q1 flow interlock defeat was removed (only required when target ladder is in position zero) |

Thursday, November 22, 2012, 17:22, Isaac Earle, Standard Operation, Target 1, Active Sump, RH Lab Active Sump Released
|
On Wednesday November 21 at approximately 9am the level of the Remote Handling active sump was inspected and found to be at approximately the 7000L
level. The high level alarm sounds at approximately 5800L. The high level alarm had been silenced by somebody, and RH staff had not been notified.
It is unknown when the high level alarm was reached. The total sump volume is 7200L (which if exceeded will cause active water to spill on |

Tuesday, January 08, 2013, 09:27, Isaac Earle, Standard Operation, Target 2, Target, BL1A Air Amplifier turned off for duration of shutdown.
|
The BL1A air amplifier has been shut down by closing the air supply valve on the device. The
air amplifier supplies high pressure air (110psi) to the following devices: M9BB, M20BB, T1 Profile Monitor, T2 Profile Monitor, T2 Collimator, Septum
Polarity Switch |
Friday, January 11, 2013, 15:48, Isaac Earle, Standard Operation, Target 1, Target, BL1A Tunnel Accessed 
|
The BL1A tunnel was accessed to drain and sample T2 cooling package water. A puddle of water was noticed in the South TNF area around the
drain by the boot-box. No water was found in the BL1A tunnel. Photos attached. |

Monday, January 14, 2013, 16:55, Isaac Earle, Standard Operation, Target 2, Target, Target Move & Damaged Profile Monitor
|
The T2-MK1 target (spare T2 target) was transported from the hot cell to the storage pit today.
While the flask was being aligned to the storage pit locating pins, the base of the flask bumped the top of one of the alignment pins. This
was caused by a slight misalignment between the flask locating hole and the alignment pin at the moment when the flask was lowered. This caused the |

Monday, January 21, 2013, 16:18, Isaac Earle, Standard Operation, Target 2, Target, T2 Cooling Package Water Released
|
The T2 cooling package water was drained to the BL1A active sump, refilled, cycled, and drained again. Samples of T2 cooling package active water
was given to RPG, tested, and approved for release.
On January 21 at approximately 4pm the full volume of the sump (280L) was released to the city sewer. |
|
Friday, April 12, 2013, 13:28, Isaac Earle, Standard Operation, Target 1, Cooling, Cooling Packages Leak Tight
|
The T1 and T2 expansion tanks were filled on Monday April 8th. There was no change in the level when inspected today (April 12th). Visual
inspection of the packages also found no leaks. |
|
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. |
|
Wednesday, April 17, 2013, 16:45, Isaac Earle, Standard Operation, Target 1, Target, T1-MK1 Target Leak Checked
|
| The T1-MK1 target was leak checked on April 15th at the T1 monolith by Ron Kuramoto and Edi Dalla Valle. No leaks were found. |
|
Wednesday, September 25, 2013, 14:05, Isaac Earle, Standard Operation, Target 1, Active Sump, RH Lab Active Sump Level Sensor Inspected
|
A notification was received that the RH lab active sump level sensor is due for annual inspection. The sensor was tested and is working properly.
The water level was observed to be only a few inches below the sensor level. Ken Buckley was notified and someone from his group will sample
and drain the tank according to the procedure in Document-64834 |
|
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 |

Friday, January 17, 2014, 10:10, Isaac Earle, Standard Operation, Target 1, Cooling, T1/T2 Cooling Packages & Air Amplifier Shut Off
|
In preparation for Edi to vent the BL1A vacuum volume, the T1 and T2 cooling packages were both shut off. They will remain off until vacuum
is restored in BL1A in a few weeks time. This afternoon, water will be purged from the T1 and T2 targets using compressed air so that stagnant water
is not sitting in the targets for an extended period of time. |
|
Friday, January 17, 2014, 15:41, Isaac Earle, Standard Operation, Target 1, Target, Water Purged from T1 & T2 Targets
|
Water was purged from the T1 and T2 targets using compressed air. The water is stored in a labeled bucket on the BL1A blocks near the T2 cooling
package. The bucket is approximately 100µSv/hr on contact and 10µSv/hr at 0.5m. Isaac's coveralls had 500cpm on them after this job and were dropped off at active |
|
Wednesday, January 22, 2014, 15:41, Isaac Earle, Standard Operation, Target 2, Water Leak, Water Drained From Suck Tube Released
|
After approval from RPG, the water drained from the suck tube, which was stored in a bucket in the RH lab active sink area, was released to the
active drain. Even after rinsing, the bucket still had a slight field from the base, so it has been labelled and will be kept in the active sink
area. |
|
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, 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 |

Monday, March 24, 2014, 18:14, Isaac Earle, Standard Operation, Target 2, Cooling, T2 Cooling Package & Air Amplifier Started
|
Bill Rawnsley completed an electrical check of the T2 profile monitor today from the Meson Hall mezzanine - All OK.
The T2 cooling package was refilled and started. There was no change to the T2 vacuum when starting the package. While running, the
package was visually inspected for water leaks - no leaks found. |
|
Thursday, April 03, 2014, 10:19, Isaac Earle, Standard Operation, Target 2, Cooling, T2 Cooling Package Resin Can Replaced
|
The resin can was removed from the T2 cooling package and transported to the warm cell. A replacement can with fresh resin was then installed.
A 12' sling and the standard four bridle was used to prevent the crane hook block from hitting the mezzanine railing on the south side.
The T2 package was started and inspected for leaks - none found. |
