TM2 has been connected in ITW. During the connection, Anders and I  found the TM2  high current cables used in ITE and CS are short in ITW.  Anders and Grant found the original TM2 ITE high current cables in target hall. We replaced them. They works fine. But, a little bit longer on cable length would be easy to connect them. All other connections and HV cover in ITW work for the TM2 so far.

 The power supply is needed as a spare for the failed TGHT p/s in ITW

I attach new Target Hall schedules here for 2015 fall and winter runs (beam schedule 129). The TH excel sheet schedule for beam 129 is included also.

Vacuum leak check on the window line circuit of TM1 took place yesterday and again to confirm this morning. Both days the response to helium is in the area of a soldered reduction fitting at the top of the containment box above and to the shutter side of the extraction column (see attached picture). To verify this morning each joint in the system had a 1 second shot of helium and then timed for 1 minute to wait for a response. This area responded both times tested at about 40 seconds...no response at any of the other locations.

Hot cell was entered for preventative mait. on left manip. field measurements around the cell were taken in prep. for window removal in January and left/south light bulb changed.

Hottest item in the cell was the conductor block end of the TM4 febiad coil line. It was 70 mSv/H on contact and seemed to be the major source of field in the hot cell. The waterblock end of this line did not apper to be hot.

Replaced the custom silver gaskets on the entrance window panel of TM1 this morning...this has eliminated an sign of leak at this joint, however there appears to still be a leak somewhere...a good distance from the vcr joints of the window as we are getting a drift response.

Chad sprayed helium to soldering stems in containment box which we suspected with leak last week. With 1second click  on helium, after 80 seconds waiting time , the LD started to show leak up to 3xe-9atm.cc/sec.

Chad sprayed helium close to service tray and vacuum chase. with 1second click on helium , after 30 seconds waiting time, the LD started to show leak up to 2Xe-8 atm.cc/sec.

After this test, we knew the leak is somewhere in service tray or service cap, but not the soldering stems in containment box we suspected before.The further investigation is needed.

 Leak check TM1 window circuit soldering stems inside service cap when module is located at NE silo. LD base LR 0.0xE-9atm.cc/sec.  Only 1 second tiny amount  helium sprayed on stems soldering joints . LD got a quick response to high E-7 atm.cc/sec.Test is repeated again with same result.  See attachments

In preparation for shipping of the spent targets five have been moved to the mini storage. The following target were moved to the mini storage, SiC#26, Ta#36, UC#9,10,11.

 will be performed Tuesday October 6th

Tuesday, October 06, 2015: Maintenance re-schedlued for Wednesday October 7th

During the weekend condition The TM4 spark at 30KV without vacuum response. It is confirmed the spark is from the top TM4 this morning.The flexible cables in a  black wire sleeve which is used for febiad X pin connection drooped too close to the TM4 surface plate, and caused the sparking. The problem is fixed by Anders and David. The cables is put back where it should stay.  After test, no sparking on the top.

Weekly update target hall schedule. See attachment 1,2.

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.

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

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

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.

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.

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.

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.

Five F-308s have been filled with the spent targets. The F-308s have been moved to the hall way between the north and south hot cell areas.
