In preparation for removing the slave for replacement I discovered that the timing screw in the handle cable drum (master side) had been left threaded into the pulley...it should have been completely removed. It was bent from hitting on a casting inside the mater arm which most likely contributed to the hopped pulleys on the slave side. After removing this timing screw I entered the north hot cell and replaced the hopped cable back onto its pulley and Isaac tested the motions that previous caused the hopped cables. These tasks were repeated 4 times without any issues. Also of note is a missing setscrew in the tong cable pulley pin and a somewhat loose tape on the slave, also the tape shows signs of a crimp/bend. Upon further inspection and comparison with the other slaves I also found that one of the "lock-down" fittings tying the Z motion tape drum to the corresponding gear is completely missing. See pictures attached.

Entry  Thursday, November 22, 2018, 14:38, Isaac Earle, North Hot-Cell, Development, , , NHC design approved by High Voltage Engineer NHCHV.pdf

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.

Paddle wheel signal was tripping proton beam in ITW. Valved off ITE dump to divert flow to ITW. Field around valve was about 600 uSv/h

Entry  Wednesday, November 14, 2018, 16:10, Anders Mjos, ITW, Repair, TM2, UC#25, ITW:FC5 safety signal troubleshooting 2018-11-13_FC5.pdf

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.

Entry  Thursday, November 08, 2018, 09:27, chad fisher, South Hot-Cell, Maintenance, , , South East Manipulator cable replacement 

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.

Entry  Wednesday, November 07, 2018, 09:50, Anders Mjos, ITW, Standard Operation, TM2, UC#25, TM2 connected in ITW 

TM2 was connected yesterday by Frank and Anders. The West side panel with IG1S on Exit Module 2 was replaced with a new SST panel with 1 CF flange only (dwg). Link to check list on DocuShare.

Entry  Tuesday, November 06, 2018, 10:59, Travis Cave, ITW, Standard Operation, TM2, UC#25, Module move 

 TM#2 with UC#25 has been moved from the conditioning station to the west target station.

Entry  Monday, November 05, 2018, 14:27, Anders Mjos, Conditioning Station, Standard Operation, TM2, UC#25, Target module disconnected 

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.

 The spent nSiC#1 target has been moved from the south hot cell to the spent target vault. It was placed in pail #172 and placed in spot 7B. See attached PDF for vault details.

Entry  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.

Entry  Tuesday, October 30, 2018, 10:50, Travis Cave, ITW, Standard Operation, TM2, nSiC#1, Modules moved 

 Modules were moved, ITW EX2 was moved from the conditioning station to the west target station and TM#2 ,with nSiC#1,  was moved from the west target station to the south hot cell.

Entry  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 between service cap steel welding frame and the whole cap top cover plate in different location . All bolts on the top plate pressing down the o-ring are very tight. I can do nothing on them. However, I sprayed some vacuum seal around the leak area. The leaks are small  and close to ITE TP1S. I don not think we have to replace it at this moment.  Basically, The module is good to move to ITW tomorrow morning.
