The heat shield water lines were not purged ahead of target exchange in the hot cell. This resulted in water leaking onto the new target assembly (heat shield) when the cooling lines were opened at top and bottom (for connecting leak detector). Excess water was wiped up with paper towels.

 Both the West Entrance and TM#2 with UC#23 have been moved back into their places in the west target station. The Entrance module move wasn't completely smooth as it did suffer a little bumpiness when the shield plug part was installed, I was lifted back out again and no visible damage was observed on the delicate items.

 Electrical Checks of the last two targets Ta#56 and UC#23

 TM#2 with UC#23 has been moved from ITW to the south hot cell. The shield plug was also installed remotely as well.

 Results of the electrical check on TM#2 with no target after Chad cleaned out the bolt hole on the module where the target mounts.

 TM#2 with the nSiC#1 target had its check done on it at the south hot cell see attached for results.

 TM#2 with nSiC#1 has been moved from the south hot cell to the west target station.

TM2 was disconnected in ITW this Tuesday. See attachment for checklist.

Tm2 with SiC nano has been connected in ITW. See attachment for checklist

UC#23 experienced short between target and heat shield as it was heated during operation. The inspection of the target after irradiation revealed that the left target leg was close to the heat shield opening and likely the cause of the short. Marks could be seen on the leg indicating contact. See attached photo. More photos are available on DocuShare

On September 18th installation of nSiC#1 was attempted on TM2. As usual, new fasteners were tested previous to insertion into hot cell and employed during installation. the last fastener to be installed was for the circuit D block. The fastener/air ratchet stalled immediately indicating a problem. The fastener was removed and a an attempt was made trying a new spare fastener. That fastener also jammed right away but could not be removed or installed any further.

A breaker bar was employed to achieve more torque and the fastener was able to be loosened, although it would not come completely out, dangling and wobbling like it was free. A claw type bar was used to add slight pressure to the fastener while it was loosened allowing the fastener to undo the rest of the way.

Target was removed and discovered that that insulator supporting circuit c and d blocks was quite broken and that a few chunks had fallen off. It was also notice that boefore the breaker bar had been employed that a piece of ceramic was on the table suggesting that the ceramic had been at least partially broken at the time of removal of the previous target. Also, the threads of the insert for circuit d showed damage an swarf.

Swarf was vacuum claned out of the circuit d thread insert and a machine tap ran through the insert twice.

nSiC#1 was reinstalled with new waterline gaskets and new c and d circuit fasteners with a little bit of the first 2-3 threads lightly coated with vacuum grease.

High current fasteners torqued to 130 in lbs.

 Modules were moved, ITW EX2 was moved from the conditioning station to the west target station and TM#2 ,with nSiC#1,  was moved from the west target station to the south hot cell.

 TM#2 with targets nSiC#1 (old target) and UC#25 (new target) electrical check results. See attached for details.

Chad and I did  leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec.   No response on LD. during helium spray.   Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec ate stopped there.  The result is close to before.

Frank and Anders disconnected the water and electrical connections this afternoon after the target was conditioned over the weekend. The heater ramping program ran with the wrong gauge selected, causing the vacuum to go higher than planned. The module will be moved to ITW tomorrow.

 TM#2 with UC#25 has been moved from the conditioning station to the west target station.

TM2 was connected yesterday by Frank and Anders. The West side panel with IG1S on Exit Module 2 was replaced with a new SST panel with 1 CF flange only (dwg). Link to check list on DocuShare.

Measured resistance on safety limit switches for FC5 on Exit Module 2. Determined that the in connected signal did not work (shows not connected irregardless of FC position). Confirmed proper operation of the OUT limit. See attachment for details. The Harp 5 x and y signal connectors were checked and reconnected.
