|
Leak checked TM4 coil1 in SHC with Isaac . The leak detector only can pump down to 1.5xE-7 atm.cc/sec. The leak detector got the response once the helium
valve is open, not even close to the leak area. The leak detector got a very big response when the helium probe was put close to the coil terminal block
on target front side and spray helium for 2 clicks. The leak detector got a small response when the probe was put close to water block area and spray |

September 18th
The wiring harness was completed by Maico and Travis today (see pics) and was installed into the target module. During installation the bracket
went on with ease. The junction box appeared to be hung up on something but did engage eventually. The plug for the collimator is not quite long enough |

Monday, September 23, 2013, 13:55, David Wang, South Hot-Cell, Standard Operation, TM3, , window circuit leak check
|
This morning, Bevan and I leak checked window circuit on TM3 at SHC after containment box was installed. It took about 20minutes to pump down the circuit
to 0.0xE-9atm.cc/sec. Bevan sprayed helium on both VCR joints and a final splash. No response had been found on leak detector. |

Today was a trying day. When attempting to make the water line connections for the window the VCR seal fell off several times. Each time this
happens the seal becomes stuck at the bottom of the containment box. While trying to replace the seal the nut slipped down the line to the bottom of |

Wednesday, October 02, 2013, 13:44, Bevan Moss, South Hot-Cell, Standard Operation, TM4, , Right Coil is leaking
|
Today Maico and Travis completed and electrical test to determine the right and left coil on TM4. The left coil is the negative side. From there
Maico pumped on both lines for a leak test. The leak cart pumped down to its lower limits on the left line and there was no response when sprayed with
helium. The right line would not pump below 2.5 x 10^-2 Torr and had a base leak rate of 3.3 x 10^-7 atm*cc/sec (this indicates a massive leak). Without |

Blocks 1-4 have been moved from ITW to ITE. Block 5 was moved to a storage area as it will be in the way of the harp repair. Danka took air samples
and found 200 counts of alpha on the air samples but nothing on the swipes. It is recommended that resporators be worn while blocks are being lifted and
lowered. She will check the monitor tomorrow to confirm it is behaving as it should. |

Yesterday I visually inspected the paddle wheel and noticed that it was spinning freely and constant. As the signal was intermittent replaced the
coil at the back of the wheel only. This does not require access to the high active water. With the coil replaced the signal looked strong. I asked operations
to keep and eye on it and advise if the problem has been resolved. I also discussed with David this morning and he informed me that this is the same procedure |

The C2 circuit (coil 2) water lines and blocks have been revoed from TM4.
Water block jig could not be used as the window water block connection was nowhere near fitting into the jig (IMG_1224 image below) and
therefore caused an interference causing the rest of the blocks to not mate with the jig. A different tool that has never been used was implimented and |
