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.

 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.

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. 

The west exit #2 module has been moved from the south hot cell to the conditioning station.

Actuator arms, lemos, lemos and banana plug block have been disconnected in preparation for raising of the service tray. Aaron has pictures

ITW RV4S (A and B) are leak checked. They are good. 

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.

TM2(SiC nano) has been disconnected in ITW. See attachment
