|
To satisfy RS 101 from the NHC requirements specification (Document-131915) Tomislav Hurskovec was consulted regarding high voltage safety. After
a verbal discussion on various aspects of the NHC design he confirmed that the design satisfies high voltage safety concerns.
A copy of his confirmation e-mail is attached in PDF format. |

|
Measured resistance on safety limit switches for FC5 on Exit Module 2. Determined that the in connected signal did not work (shows not connected irregardless
of FC position). Confirmed proper operation of the OUT limit. See attachment for details. The Harp 5 x and y signal connectors were checked and reconnected. |

|
The handle cable on the east manipulator of the south hot cell has been replaced. Old cable showed signs of wear but had no broken strands. Manipulator
is back together but still needs to be re-tensioned. |

|
Frank and Anders disconnected the water and electrical connections this afternoon after the target was conditioned over the weekend. The heater ramping
program ran with the wrong gauge selected, causing the vacuum to go higher than planned. The module will be moved to ITW tomorrow. |

Thursday, November 01, 2018, 11:42, David Wang, Conditioning Station, Standard Operation, TM2, UCx 25., TM2 HS line helium pressure test at TCS and helium spray at SHC..
|
Chad and I did leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec. No response on LD. during helium spray.
Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec
ate stopped there. The result is close to before. |

Monday, October 29, 2018, 10:43, David Wang, Conditioning Station, Repair, , , ITW exit 2 leak check at TCS.
|
I did a leak check this morning on exit 2 module at TCS. LD base leak rate is 4.00XE-9atm.cc/sec, Base pressure is 0.00 X E-4 torr. All seals,
bellows, and flanges are checked. The new FC5 bellow is good. There is a big leak up to 2X E-6 atm.c/sec has been found on IG1S side panel . The panel
itself will be replaced this time. Machine shop is working on it.. Two small leaks in E-9 atm.cc/sec range have been found on the o-ring |

|
Cover 1 was removed from the exit module. Confirmed with David that the actuator rod that needed to be disconnected was the far left )as viewed by the
hot cell operator). The fastener for this rod was un-accessible from this side. Cover 1 was re-installed (two bolts left loose) and cover 2 was removed.
fastener holding the actuator together was removed and luckily it does have a remote start. |
