Both Turbo pumps on TM3 have failed. They were both attempted to start in soft mode. TP2 could only achieve ~19kpm and TP1 ~10kpm. I have
turned off the scroll pump and vented through the turbo pumps. |

Tuesday, October 25, 2011, 16:57, Bevan Moss, Conditioning Station, Standard Operation, TM4, , Turbo Pump 1 issues
|
Roughing on TM1 started at ~15:00 today by ~16:30 the module had reached a pressure of ~200 mTorr and the turbo pumps were turned on. TP1 failed to achieve
normal operation and we running at approximately 4KRPM and 50W with 6.1 A of current draw. TP2 was able to achieve normal operation. The controller for
TP1 was then powered off and back on but that failed to resolve the issue. The controllers for TP1 & 2 were then switched at which point TP1 again |

|
Over the weekend Turbo pump one failed. It was attempted to restart the turbo in soft start but that also failed. Although the Vacuum was good
enough to operate both Turbos are required to pass commissioning. As such the pumps were turned off at ~10:00 today. Venting started at 12:00. |

|
Turbo Pumps have been started and are in normal operation. TP1 which has recently been replaced was started in soft start and had no issues. TP2
was started normally and tripped prior to reaching speed. It was left for a while and restarted. When restarted it was still at 17KRPM, it reached normal
operation. |

|
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. |

|
This morning new water block fasteners and gas line capture nut fasteners were inserted into the hot cell. Window waterline blank off was removed from
TM2, surfaces inspected and given a polish with Veltex (30 seconds, 70 psi) as there was a small bit of c seal residue. Transfer try with new source tray
has been latched to the module. |

|
Repair of the tray transfer fixture is complete (minus testing).
A distorted ball nut lock plate was replaced and thread loc added. to the ball nut/plate assembly. Testing will take place tomorrow once the thread
lock has a chance to cure. |

|
Transfer fixture has been remotely disassembled to the point where the ball nut lock plate assembly can be inserted into the tool port and the plate
replaced by hand in the tool port without having to enter the hot cell. Straight head screws will be replaced with SHCS to facilitate easier re-assembly
and future disassembly. |

Monday, January 22, 2024, 10:16, David Wang, ITE, Standard Operation, TM4, UCx#, Tm4 waterlines helium pressure test and TM service cap helium leak check.
|
Tm4 waterlines helium pressure test and TM service cap helium leak check was done last Friday. All water lines were pressurized with 70psi helium for
3 minutes each. The 3 minutes stable leak rate on all lines are less than 4.0 X E-9atm.cc/sec. some of lines had surging leak rate to 2xE-8 atm.cc/sec
at the first 10 seconds of pressurization which should be a gas hammer result at the beginning. Based on the numbers, I would say all water lines are leak |
