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.

 TM#4 has been moved from the east target station to the south hot cell.

TM#1 with TaC#1 installed passed the electrical test. With a value of 882MOhms that was meggered from the heat shield to the chassis, all other measurements are within spec.

Move of TM#1 with the TaC#1 target has been moved from the south hot cell to the west target station.

TM#1 with TaC#1 from the west target station to the south hot cell. Move went well.

November 15, 2011 removed TaC#1 from TM1 and inspected TM1 for any obivous signs of trouble (Problems with EE at end of run).

Upon starting removal of the high current conductor fastener on A+ (Left oven leg) it became clear right away that the oven of the target was broken as the leg moved as soon as the fasten was loosened.

Inspection of TM1 with the target removed yeilded no obvious signs of trouble, save a piece of capton tape found on the sliding tray directly below the service tray.

Inspection of TaC#1 showed that the oven was indeed broken on the A+ (left oven leg) side of the central block.

TaC#1 was moved from the south hot cell to the storage vault. It was placed in pail#92 and put in vault slot 7B. It was 239mSv/hr upon removal from the south hot cell.

I disconnected TM4 in ITW .The job took about 20minutes and I got 0.11 msv dose.

Chad and I did a leak check on heat shield circuit after target is installed on TM1.The leak detector pumping down is smooth. The base leak rate is 0.0xE-9 atm.cc/sec. The base pressure is 0.0xE-4torr. Chad checked helium flow downstairs and sprayed helium to each joints for 2 seconds.The first joints is good and there is no any response on leak detector.we double checked it again and got the same result. On the second joint, Chad sprayed helium 2second. After 15 second of spraying,the leak detector got a response which climbed to 3.2xE-8 atm.cc/sec max,and back to 2.5 XE-8 atm.cc/sec. Chad tried to tighten the fitting. During his tight, the leak rate response to 7.5x E-8 atm.cc/sec momentarily. After the tightening ,the leak rate back to 0.0x E-9atm.cc/sec whic is the base.So we sprayed the helium to the joint again.This time ,there is no any response on leak detector. We checked this joint  again and got the same result which is no response. Finally, Chad flush the helium around the target for 10 second ,and during 45 sec observation time there is no any response on leak detector. I would say the heat shield circuit is leak tight so far. I will do a helium pressure test on it once the TM1 is moved the CS.

TM1 was moved from SHC to the TCS. The mode took roughly 1 hour. During the move the north east corner of the containment box caught slightly on the flange of the vacuum vessel and then slipped off. The contact was minimal but should none the less be noted. After sliding off of the flange the module did not crash into the other sides of the vacuum vessel, this is why I believe the contact was minimal. It should be noted that the corner of concern is the one that is most difficult to see.

I connected vacuum system to TM1 and conditioning station and started two turbo pumps yesterday. The pumping an d vacuum readings  are verg good so far(all below 5xE-6 torr). Helium pressure test on heat shield circuit will be fulfilled next week.

Megger checks were exceptionally high (good).  Readings taken less than 2 hours after reading low values from end of run on Nb#6.  Tests on Ta38 will be repeated at conditioning station later.

Connected leak detector to TM1 and CS vacuum system. The vacuum readings on TM1 and CS:PNG1 1.3 xE-6 Torr, IG1 4.7xE-7torr, IG4(diagnostic box)1.5xE-6 Torr. Leak detector base pressure:0.0xE-4 torr, base leak rate: 0.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 5 mins . There is no response on leak detector. The heat shield circuit is leak tight.

 We moved TM1 to ITW today, I connected TM1 to ITW, and started all turbo pumps this afternoon. TP4s is very difficult to bring to 38 KRMP now. I have to use soft start model and tried twice to get this pump started (1.5 hours). This pump always had a difficult start time during the past 2-3 runs. I talked with Friedhelm and we think it should be replaced after this run. I will issue an e-fault on this pump and try to get a new pump from vacuum group. It will take 2 hours to change this pump. I could do this job with another person help. Or, vacuum group could do it. Don can schedule a time for this job before next run. Anyway, it should work fine for this run.  The water interlock check related to TM1 is done. I will do the rest before blocks on. All TM1 water signals are strong and good. All vacuum gauge readings are good so far(below5.0xe-5 torr).

I disconnected TM1 in ITW.  Heat shield line has been purged .

Ta36 was check by Maico and Chad.It was then carried into the anteroom.From the anteroom it was transferred into the south hot cell.

Tm2 has been moved form SHC to ITE. The move is smooth.

September 5, 2024 -AT

• Plastic and clean target tray added to SHC 
• TM4 moved to SHC 
• TM4 containment box cover removed

September 6, 2024 - AT

• Ta#68(Spare) removed from TM4 onto clean tray 
  • top left mounting bolt fell under source tray in containment box - unretrievable
• Ta#68(Spare) moved out of SHC via toolport door 
  • SHC lift table was lower than tool port tunnel by 2". Target-on-Tray slipped back onto lift table when trying to drag it up to the tool port. Target bounced out of one locating pin, but stayed within boundaries of the tray 
  • Water also leaked out from the VCR fitting and on to the SHC lift table, and toolport. 
• Target-on-tray slid into a clean plastic bag, and then into a plastic box. 

 September 9, 2024 - AT

• Ta#68(Spare) taken out of plastic bag and water drained from waterlines
  • Target was rotated in every direction several times until no more water poured out from the VCR joints
• Ta#68(Spare) put back in box without the bag (to promote evaporation) 

 Target Ta#68 loaded onto TM4 

-leak check passed

-Target electrode conductor screws torqued to 130 in-lbs

-electrical check passed

Containment box cover re-installed
