|
The handle cable on the east manipulator of the south hot cell has been replaced. Old cable showed signs of wear but had no broken strands. Manipulator
is back together but still needs to be re-tensioned. |

Entered hot cell to preform replacement of slave tong cable. Existing cable shows no signs of wear so it has been re-installed. A spare tong cable has
been loaded into a spare tong while in the hot cell in preparation for next time this cable needs to be replaced. |

|
Field readings have been taken at the south hot cell in preparation for entry into the cell to fix manipulator.
Field on contact at aluminum cover is 66 uSv/h, and a pole monitor into the cell through the tool port read 297 uSv/h. |

|
The old TM#2 source tray and TM#4 optics tray have been removed from the vault and placed into the spent target storage on tray 9 which is meant
for source trays. |

Two minor chips in the main 60 kV insulators on the source tray was inspected today by Anders, Tom and Aurelia. The chips are small enough that
they should not be a problem. See photos for details. |

TM3 Rev 2 source tray/extraction column insertion into its storage was completed yesterday and it was then removed from the hot cell and put into
the anteroom until June 25th when it will be moved into the vault tunnel.

|
The Source tray was inspected in the RH shop today by Anders, Friedhelm and Jens. The routing of the lines are satisfactory, however a design proposal
to remove the ground electrode line will be made. This design will have to ensure a proper connection from the electrode to ground (using the window cooling
lines). All other lines are OK at this point. Some fine adjustments are expected after brazing and soldering to maintain high voltage separation. Photos |

|
Chad removed the source tray from TM3 today, see attached picture (video was also taken). There was some interference between the window cooling
lines and the frame work as well as the clamps for the ground electrode and the water block alignment jig. There was also interference between the optics
alignment post (specifically the mushroom top) and the water block alignment jig. Investigation into these inferences needs to be completed as they could |

The two 45 gal (m) drums of waste removed from the south hot cell in December 2015 and January 2016 were transferred from the north hot cell to the shaft
of the east vault tunnel on Monday, July 25th 2016 and subsequently to the east tunnel bunker in the vault tunnel on Tuesday, July 26th, 2016.The first
drum (removed from the hot cell in December) containing both activated and contaminated metals was measured at 900 uSv/hr @ .5 m and the second drum (removed |

Field measurements have been taken to determine the level before entry for repair of manipulators.
Field on contact at manipulator is 560 uSv/h, and at approximately 1/2 meter at table surface 920 uSv\h. |

Thursday, July 06, 2017, 14:23, Isaac Earle, North Hot-Cell, Repair, , , Slave side Z motion tape snapped on NHC right side manipulator
|
The NHC right side manipulator was evaluated today to check if operation was normal through all ranges of motion. The manipulator was first moved
through usual motions without the electric motion drives: the feel was fairly normal, a sound could be heard from the master side Z motion tapes rubbing
on the sides of the pulleys, this problem had been identified a few weeks ago however it was significantly reduced since the master side upper and lower |

|
Sorted and packed one 55 gallon drum with low contamination and active stuffs which are placed around silo area in the past. They include old poly water
cooling lines replaced from ITE, ITW and TCS, contaminated paper rags , gloves, and plastic bags,air cooling fans for turbo pumps, EE resistor packaged
used on module top before, flow meters and cables used in ITW, etc. After packing, The field outside the drum on contact is less than 10 usv/hr. |

|
Just some notes on the install of SiC#30 on TM3 last month...It was installed with all new fasteners and torque values provided by Anders were used...of
main interest is probably the main high current fasteners which were torqued to 150 in lbs. |

|
Looked at SiC#45 in the hot cell. Looked very clean, no deposits on the heat shield or other components. Target also looked very straight. Only issue
we saw was sparking marks on the EE side that faces the ground electrode, in several spots. This target had a bout of sparking when ramping up the protons,
so I guess that was the location. Will look for matching spark marks on the ground electrode next time TM4 is in the hot cell. Forgot to take picutres... |

|
Sic#35 has been installed onto TM2. High current fasteners torqued to 130 in lbs.
Mating of the 9 pin connector was extremely problematic but in the end I was able to get it to mate properly. Noticed left (when facing module
in hot cell) febiad coil left twisted a bit when torqued up. |
