TM#4 with UC#26 has been moved from the south hot cell to the conditioning station.

 Electrical check of TM#4 with the old Ta#57, no target and with new IG-LIS UC#26 target. See attached PDF for details.

Inspected new high current flexible cables during TM4 disconnection. The new cables and adapters work fine.

TM4 was disconnected in ITE. Checklist list in attachment.

Ta#57 has been removed from TM4.

 TM#4 with Ta#57 has been moved from the east target station to the south hot cell.

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.

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.

Yesterday Diagnostics group installed a temporary external limit switch to provide the in signal to the safety system.

Frank and Anders moved blocks from ITE to ITW yesterday

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

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.

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.

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

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.

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.

 TM#2 with targets nSiC#1 (old target) and UC#25 (new target) electrical check results. See attached for details.
