Dan and I replaced pedal wheels and coils on ITW water flow sensors. It is a shut down job we did every two years. See attachment for detail.

TH shut down activities schedule from Feb 23th-March 25th. The schedule will be updated each week. See attachment 1.

Feb-27-2015: Updated the schedule, and uploaded as PDF file. See attachment 2.

See attached report.

Summary:

Radio problems just before entry to cell. Inspection afterwards revealed batteries charge but battery in one radio shorts out after a couple loads/cycles.

Fields in hot cell range from 630 uSv/h @ 1 m to 1.5mSv/h @ 1m. Contributing to the fields is the febiad coil line removed from TM4 in the south west corner of the hot cell.

Contamination/particulate on table as mostly black colored and of a fairly substantial size, but seamingly easy to collect. Distinquishable pieces of target material present.

Hot cell window show no sign of leaking on the inside of cell.

Pre-filter changed.

Manipulators lubricated.

Hot cell entry procedures appear to still be fairly successful in minimizing contamination migration from the hot cell.

TH shut down jobs are processing as scheduled this week. Discussed with Don, and we think the jobs scheduled in next week should be processed as we planned. See attachments for updated schedule.

I updated the schedule today. See attachment 3, 4 for updating.  2015-Mar-10.

2013-Mar -13, I updated the schedule to show the jobs we finished this week. See attachment 5,6

Box for dissecting targets almost complete. Should be done tomorrow.

3 swipes of the south hot cell table were taken from the target hall through the roof hatch (2 standard, 1 alpha).

Initial results of the table swipes are pending however swipes of the pool tool and end effector are clean, 0 counts, booties, gloves clean.

Fall arrest equipment has a puzzling 6000 counts, and suit 500 counts.

The ThO#1 has been placed in the storage vault placed in pail #122 in spot 2B of the vault. It was 6.2mSv/hr upon removal from the south hot cell. see attached PDF for details.

The spent UC#11 has benn moved from the south hot cell to the spent target vault. See attached PDF for details.

Final assembly and alignment of TM2 optics tray continued today. Front section is "aligned".

This schedule is following Dons schedule on module moves. See attachments for updating.

2015-03-27: Weekly update the schedule. The shut down job is close to the end. See attachment 3, 4.

Ta#45 has been inserted into the hot cell. Swipe taken of inner tool port area: 100000 counts/min.

TM2 optics tray build is continuing. Going well. Hope to have assembly and alignment finished by Friday.

See attachments 1, 2 for target hall schedule from 07 April to 26 June 2015. The first TM1 move which is scheduled on 16 April 2015 could be delayed because of SHC operator availability. I will update the schedule once Don confirms the move date with Isaac.

Updated the schedule. The TM1 move has been re-scheduled to Friday, 17 April 2015.    See attachments 3,4.

The following variable have been added to the archiver (as per work request)

The archiver was restarted.

The new TBHT and TGHT power supplies were brough up to high current; 350 A and 420 A respectively. The TGHT power supply was limited by PLC to 420 A. The resistance calculated for both the TBHT and TGHT copper lines from the electrical services room to the ITW pit was 1.35 mOhm. See attached spreadsheet for details.

Dave Morris has been contacted to correct the current limit for the TGHT supply to 600 A.

Caled cyclotron ops to open P23 and confirmed penthouse valve open.

Filled up TK2 to 21 in water leve.

 The communications chip has been replaced. The electronics box has been grounded (see attached pdf).

I revised the Target Hall schedule to July 21 2015. It is the time new TM2 with ZrC target started at ITW.

2015-06-04, Updated the schedule with   new PDF view. See attachments 3, 4

TM2 new source tray has been remotely transferred into SHC successfully. The transfer table has been moved back to TH within 1 hour.  I swiped the table and found about 150counts contamination. It is much better comparing to last time using since we removed this table out of SHC as quick as we can. The table will be cleaned with windex  after Target Hall is surveyed.

Weekly update Target Hall schedule 2015-06-15. See attachment 1,2

 2015-06-19, Update the schedule on  the end of the week. See attachment 3,4
