Updated schedule this morning after last Fridays ISAC facility support group meeting.

Updated schedule on 2015-April -02. See attachments 3,4. The scheduled all shut down jobs are done on time.The TM2 move to SHC will be delayed to May.There will be a new beam running time TH activities schedule (start from April 15) replacing this shut down schedule on next time  weekly update.

TM4 has been connected at CS which includes high current cables, water lines, EE cable, and Enizel lens cable. The HV cover has been  installed onto the TM4 service cap.The CS water system is started. All water signals are good so far.   Anders will start  HV and heaters conditioning on next Monday.

The helium pressure test on TM4 HS line at conditioning station is done. No leak. I also leak checked all vacuum seals on TM4 service cap. They are all good.

Electrical check of TM#4 with Ta#45 at the conditioning station, see attached pdf for details.

I connected TM4 and CS vacuum system after TM4 move. CS roughing pump was started first this morning. Later, Anders, Bill and I started 3 turbo pumps on TM4 and CS. The pumping down is good so far. The CS vacuum system ion gauges are turned on also.

Chad and I leak checked TM4 HS water line with new Ta#45 target installed at SHC. Leak detector base leak rate 0.0Xe-9 atm.cc/sec, base pressure 0.0Xe-4 torr. Chad sprayed helium twice on each of HS 2 VCR joints.No leak has been found. The joints are leak tight. The helium pressure test  will be done at CS later.

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

TM#4 electrical checks with and without the target installed, installed target is Ta#45.

Ta#45 has been installed onto TM4 and is ready for leak and electrical check. High current fasteners torqued to 130 in.lbs.

TM#4  with no target has been moved from conditioning station to the south hot cell.

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

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.

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

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

TM#4 from south hot cell to the conditioning station no target is attached to the module.

TM#4 with UC#11 moved from the east target station to the south hot cell.

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.

Chad, Anders and Alex inspected the target this morning. The target had no significant visible damage to the container. Some material was deposited on the Extraction Electrode.
