|
TM3 has been disconnected this morning and purged all HV water lines. I found the power plug for all turbo pump fans wasnt connected during
the last run. That maybe the one of the reason on that ITE TP3 failure. |

Thursday, November 21, 2013, 12:12, Anders Mjos, South Hot-Cell, Standard Operation, TM3, NiO#2, End of beam target inspection - ANODE does not hold 250V
|
The target was inspected by Chad and Anders in the Hot Cell. Electrical megger tests were done during the assembly. It was found that Insulators No 3
(ITD0311) and No 2 (ITD0310) failed to hold voltage after the run.

Wednesday, November 27, 2013, 12:50, Bevan Moss, South Hot-Cell, Standard Operation, TM3, , Ground devices wiring check
|
Travis and I completed an electrical check on the wiring harness for the devices on the ground plane. All lines passed 500V with the megger except
for PNG and the BTM steerer. Those devices had a short to ground. of ~1.4ohm. |

|
Maico removed the containment box today allow Travis and I to further test the wiring harness. I disconnected the junction block and Travis and
I repeated the test from yesterday. The all lines except the PNG tested OL. The module was then lowered and the twisted pair connected to the pin that
corresponds to the steerer labeled BTM (it is likely this is not labeled correctly). This testing showed showed that the source of the short found yesterday |

|
Using in cell camera and transit the suspect line on the steerers was inspected as best as possible. An existing photo of the complete steerers before
installation was used for comparison. The wiring and beading inspected today showed no obvious problems, breaks or spots where there may be a short. In
comparison to the photo from construction, what we could see of the steerers looked identical to the original installation. |

ITE and TM3 Turbo pumps have been started successfully yesterday. The vacuum reading on all ITE high vacuum gauges are at low E-6 range after one night
pumping down which are good so far. There is no any sign of leak on BL2A window and the flange seal on ITE side. Yesterday afternoon, Ron , Edi ,and I
did a leak check on the ITE BL2A window flange(2aTunnel side). The leak detector was hooked onto BL2A in tunnel. Ron and I supplied helium from TH |

With TM3 located in ITE, All air to vacuum seals on ITE primary and secondary vacuum vessel have been leak checked with leak detector hooked
directly on the TM3 service cap.The base LR :00xE-9atm.cc/sec. The ITE IG1 was 1.6xE-6 torr which was good. No leak has been found during the checking.Also,
the TM3 water lines(except HS) had been pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. The ITE and |

TM#3 electrical check at the south hot cell with no target to give us a base line and show that things are ok with the module for the start of
the running year. |
