The repair/cable replacement on the east manipulator is now complete.
Yesterday's initail cable replacement went very well however, due to a minor glich, we were unable to test the tong movement until I was out of
the hot cell. Tong did not fully close and felt like there was a "hard stop" at a repeatable spot in the closing of the tong. Upon further |

|
Chad and I leak checked TM2 tube heater(+) water line yesterday afternoon. The water line was difficult to pump down on base leak rate, but LD
base pressure was fine . The base pressure on leak detector was pumped to 0.0XE-4 torr quickly. The base leak rate only could be pumped to
4.5 xE-8 atm.cc/sec after 1 hour waiting time. All vacuum connections to leak detector in the target hall were leak checked and they were good. Chad |

Chad and I did a pressure test on TM2 tube Heater+(D) water line.I pressurized the D line with shop air from quick connectors(both ends) on service cap.chad
applied bubble soap onto the D water block in SHC. The test started from 5psi,and increased 5psi each time to 40 psi. From 5 to 35 psi, no bubble has been
found on water block. At 40 psi , bubble appeared from blind blank off seal , but not from soldering joints. Since the o-ring seal for the blank off is |

Bevan and I did a leak check on TM2 tube heater+ from inside service cap in TH. The leak detector base leak rate 0.0xE-9 atm.cc/sec, base pressure
0.0xE-4totrr. One of side panel on service cap was opened. Bevan sprayed the helium to the "D" line inside the blue insulator.The helium flow
was checked , and he sprayed twice. No response has been found on leak detector. See attachment pictures |

|
Chad and I did the Leak checked TM2 tube heater (+) water line with rubber insert plugged water block on " D" in SHC. The
Leak detector was very easy to pump down to the bottom leak rate and pressure. Chad checked the helium flow in SHC, and sprayed 10 second helium on
the block. There is no response had been found during the test. The test was repeated again and no leak has been found. See attachment pictures. |

I did the helium pressure test on Tube heater+ line this morning. The vacuum on CS and TM2 are very good. The base lake rate on leak detector was 1.7xE-7
atm.cc/sec. Base pressure was 0.0xE-4torr. I applied helium to the "D"line .The test started from 30psi up to 80psi on both side "D"
