ZrC#7 was transfered to a spent target disposal pail today and removed from the hot cell. The "hot" end of the TM4 coil end was also disposed of in the same pail (#129)

Six F-308's where received from Nordion #6,#15,#13,#16 all contained contamination. Loose contamination was removed with some fixed contamination remaining levels are low enough to allow the transport of spent targets. flasks where serviced as per Nordion Document IS/PP 0009 F308, IS/PP 0981 F308. Flasks are now located in the north hot cell area.

The failed extraction electrode was inspected in the hot cell this morning by Anders and Chad. The following electrical measurements were taken

• EE on target assembly as recieved from TM after online operation. 14 Ohm
• EE removed from target assembly and placed on conductive flat surface. ~1 G-Ohm at 1kV
• EE installed back onto target assembly (fasteners not tightened).~ 0.8 G-Ohm at 1 kV

There was some material deposited on the EE. Some of which has fallen off - possibly during removal of the electrode from the target assembly. It seems the cause of the short was material build up between plasma electrode and extraction electrode. See photos.

The heat shield lid was removed after lunch. This revealed a broken target. The target may have broken after operation (in hot cell).

Rebuild handle of manipulator serial 7986 (currently in the east position) and replaced broken snap ring 5555-18h on west side of the handle underneath motion switch.

The febiad coil line removed from TM4 has been cut into pieces small enough to be disposed of in a 5 gal pal. The line was cut with a Ridgid Model 104 manual pipe cutter (using the manipulators of course).

This pieces constitute the bulk of the field in the hot cell and will be disposed of with the next spent target.

Lower and disconnect TM2 from crane in ITW, proceed with hooking up TM2 as per checklist with Anders. Double check flow meters and coils, reset TP1 and TP2

TM#2 with SiC#32 has been moved from the south hot cell to the west target station.

 An electrical check was completed by Travis C and Anders M. Note ~250 kOhm between Target and 60 kV common. Leak check was done by Dan M and Chad F on HS and Window circuits. No leaks found

SiC#32 has been installed on TM2. High current fasteners torqued to 130 in lbs.

The TM2 containment box was removed this morning for installation of the 9 pin connector...connection.

The 9 pin connector copper tube connection was made and Anders advised on routing of the cable to the banana plug water block connection.

Short was diagnosed (short disappeared when water block was pushed slightly towards center of module) and thicker Ultem spacer installed and tested again. All good.

I did a TM2 no target electrical check at SHC this morning. A to RU at 500v  is 250K which is low.   anode- x pin is dead short to 60kv bias. RU is dead short to 60kv bias( as before).   see attachment

I installed a set of new high current cables for TM2 Febiad run. The top of TM2  is configured to Febiad mode. See attachments

ZrC#7 has been removed from TM2. Everything looks good.

I did an electrical check on TM2 with ZrC #7 on it. The EE is short to 60KV bias. See attachment

Bill and I remotely removed TM2 from ITW to SHC. The move is smooth.

Dan and I disconnected TM2 in ITW this morning.

Weekly update schedule. TM3 evaluation schedule in Nov is added.  

update the schedule after  the cancellation of TM2 from SHC to CS trip.see attachments 3,4

Bill and I moved TM3 from SHC to NW silo with a dummy febiad target installed on it. The move is smooth.

David Wang and I did the service cap inspection in target hall: see WP I2015-10-06-10.<br>

Signs of sparking were seen underneath 3 insulators: E ("Cavity"), A ("Oven+") and B ("Oven -") at the pair water lines coming out of the  feed-through and going to the HV chase. Specifically one water line of E is very close to the feed-through insulator (2-3mm gap) and here the sparking sings are more prominent: see picture.
