|
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. |

|
High active water system was checked before restart. A small water leak on resin can supply valve was found. It is fixed. MP1 and MP2 were
started and checked separately. System pressure and flow rate are normal.MP1 is in operation now. |

|
Stopped MP1 today in preparation for the power outage over the holidays. both P-25 and P-26 breakers have been switched off to prevent inadvertent start
of system |

|
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 |

|
The TM2 HS line was leak checked at SHC yesterday . 0.9xE-9 atm.cc/sec.Helium sprayed by Chad, NO leak. It was helium pressurized at TCS this morning.
Leak rat:2.5 XE-7 atm.c/sec. The result is same as last time check. No concern. |
