|
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. |

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 |

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 |

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.

|
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. |

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 |

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.

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. |
