TCS and Tm1 vacuum pumps are switched off this morning. TM1 TP1and TP2 work fine during this test period. Tm1 will be moved back to silo this morning.
TM1 IG1 stopped work during the test period. It could be broken. We will only replace this gauge if TM1 is used in ITW again. |

|
The old resin tank has been stored in silo since last year March. Without crane the tank up, We use the pole monitor measured the field around
the bottom of the tank in silo. The average contact field on the bottom is about 4.0msv/hr. @0.5meter , the field is about 900usv/hr. It is still
too hot to remove it. |

|
TCS:IG1S is reporting vacuum levels that seem to be too low (1E-10 to 1E-8 Torr). The gauge was connected to the controller for IG1, which showed the
same value. A degas was performed for ~5 min. |

|
The power to the crane and controls were turned off using the power switch in the Crane Control room. The main disconnect switch in the target
hall was not touched.
All site power will be off for a period of time during the Christmas break and this removes the crane from any issues when power is restored. |

Wednesday, December 13, 2017, 15:32, Anders Mjos, Assembly/Bench Test, Maintenance, TM2, , Source Tray inspection
|
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 |

Pete Dudley, manipulator service technician from CRL, was on site from Nov 27-30 to service the NHC Model N manipulators (See E-log entry #1578 for background).
He began by evaluating the motion selection and electric drive of the manipulator installed on the blue service cart. This manipulator had
chip A0166R01, same as the right side manipulator which had the failure described in E-Log 1578. Pete noted that the arm was very slow to switch |
