TM#4 with Ta#50 has been moved from the south hot cell to the conditioning station.

Chad and I did a leak check on TM4 HS line with new Ta target installed. Base leak rate 0.0xE-9 atm.cc/sec. base pressure 0.0XE-4.   splayed 2 helium to each VCR joints and did 10 seconds helium flush. No response on LD during the test. The HS line is leak free so far. It will be helium pressurized at TCS later.

TM4 was disconnected at ITE this morning. It was moved to SHC  after. No alpha alarm issue has been happened during and after move. The ventilation pumping down procedure on ITE was fulfilled during the move.

Update TH schedule after job delay on TM2 Febiad target. Everything should be back to schedule on last two targets. See attachments.

All turbo pumps are started. Two gas valves for Febiad run are opened. Pumping down is good so far.

Results of the electrical check of TM#2 with no target after the repair and with the SiC#35 mounted on the module.

Chad and I did the leak check on TM2 heat shield line. LD base leak rate:0.0xE-9atm.cc/sec. Base pressure:0.0X E-9 torr. The line is leak free.

Sic#35 has been installed onto TM2. High current fasteners torqued to 130 in lbs.

Mating of the 9 pin connector was extremely problematic but in the end I was able to get it to mate properly. Noticed left (when facing module in hot cell) febiad coil left twisted a bit when torqued up.

conductor insulators itd0053 and 54 have been replaced on TM2. All fasteners (1/4-20 x 1 1/4 vented) torqued to 60 in lbs.

TM#2 has been moved from the south west silo to the south hot cell.

Maico entered the hot cell and re-strung the skipped cable back onto the pulleys this morning. Manipulator is now operational.

During target removal on Wednesday October 12th, the left target heater conductor bolt (ITD0058) could not be removed. The bolt was found to be stuck in the threads (keensert) of the TGHT conductor block (ITA0583). In the process of attempting to remove the bolt, the conductor insulator (ITD0054) cracked (ref assy ITD0052). To allow increased torque to be applied and support the conductor block, a clamping jig (ITD0612) was designed and fabricated. The jig was assembled and it's function tested on the ISAC Test Stand on Friday 14th. On Monday 17th the bolt could be removed using the clamping jig and a socket wrench with an extended handle.

The threads on the removed bolt was damaged. A new set of bolts were therefore prepared and a tap was run through the keensert to restore the threads. The threads in the conductor block was tested and found to be OK using a new bolt.

The spent target could now be removed. Unfortunately the right manipulator failed during installation of a new conductor insulator, which forced the repair of the insulator and installation of the new target (SiC#35) to be postponed until the manipulator can be repaired.

Broken cable has been replaced however a cable has hopped some pulleys inside. After two hours in cell the job was stopped with cables still off pulleys. Alternate tooling will have to be made and the job will continue Monday.

 The HV enclosure and module connections were inspected by David and Anders on Wednesday 19th in an attempt to find any HV problems causing the high leakage current. One cable was cable tied to a copper conductor in the chase. Some small pieces of loose material were removed. No obvious problems could be detected.

Ta#49 has been removed from the south hot cell and placed in the storage vault. It is in pail 146 and in spot 6A.

TM#2 has been moved from the south hot cell to the south west silo.

Argon venting is started

TM2 was disconnected at ITW. 3 water circuits in ITW gave been looped to keep 75 GPM water flow to ITW. HS line was purged at HS. RPG got the water sample.

TM#2 with Ta#49 has been moved from the west target station to the south hot cell.
