TM#2 with no source tray has been moved from the north east silo to the south hot cell.

Containment box has been removed in preparation for wire replacement.

Target Hall Scheduled Activities  April 07 - June 26  2015 update.      2015-05-01. All TH scheduled jobs are finished on time this week.

Old wiring was removed yesterday, new wiring run thru the vacuum chase. Old IMG gauge removed today, new cable trays installed and wires installed into cable trays.

Wires for TM#2 steering elements, and png gauge have been run down to the containment box level. Chad has placed them in the little cable trays. Slack has been pulled back. and termination of the wire will be done on the 7th of May. A modification was done to the signal line of the png gauge wire ultem block, as grounded screw was inserted to allow for strain relief so the end would hopefully quit breaking. See attached pictures for the details.

Wires in TM#2 have been terminated at the top of the module.

The schedule has some changes due to  new TM2 source tray coil cooling line leaking at test stand. Now,It is re-scheduled in such an estimation  that TM2 source tray could be ready at teat stand by this Friday(May-15th). see attachment 1,2.

2015-05-12,  Changed  and updated the TH activity schedule according to Dons new beam schedule which is re-arranged after the coil line leaking issue. See attachments 3,4. No major conflicts has been found on the new schedule.

2015-05 25, Updated the TH activity schedule according to present TM2 job processing. See attachment 5,6.

TM2 has been successfully de-shuttered.

All went pretty much according to plan except I had to remove one fastener out of the upper wiring harness (the one that has just been installed) to allow for enough clearance to rotated the shutter guide out of the way...I shutter to think what would have happened otherwise...anyways...

Close inspection of the shutter does show that the "thin" area isn't in very good shape; whether this is a result of removal or just the way it was is hard.Due to the ease of removal I would quess that it may have been a preexisting condition. That being said...I think we may want to consider replacing it.

The shutter in TM2 was successfully replaced today.

New lock washer and nut were installed onto shutter and nut torqued to 120 ft lbs.

Shutter guide alignment tool was used to insure tapped shutter guide holes were concentric with thru holes in shutter side mounting panel, button head screws replaced and torqued to 110 ft-lbs.

The shutter was manually cycled open and closed by David and everything is to operate well.

Post beam electrical check on the Ta#45 target installed on TM#4. See attached PDF.

Target Hall schedule weekly update. All jobs are finished on time so far.

Ta #45 has been removed from TM4 and SIC#31installed.

Electrical check on TM#4 with SiC#31. See attached PDF for details.

Chad and I leak checked TM4 HS water line with SiC #31 target installed. leak rate:0.0xE-9atm.cc/sec.  No leak.  The line will be helium pressurized at CS later.

2015-06-03, helium pressure test the line at CS. 70psi 3 minutes. leak rate 0.0xE-9 atm.cc/sec. No leak.   See attachments

TM2 new source tray has been remotely transferred into SHC successfully. The transfer table has been moved back to TH within 1 hour.  I swiped the table and found about 150counts contamination. It is much better comparing to last time using since we removed this table out of SHC as quick as we can. The table will be cleaned with windex  after Target Hall is surveyed.

TM#2 is now in the south hot cell.

As per scedule TM2 containment box has been removed.

Today cleaning and polishing pads were inserted into the hot cell.

Module side waterblock jig installation was attempted however one of the locking tabs/latches (ITA2405?) came undone/fell off. Luckily, I had old, obsolete jigs in the hot cell so I was able to remove parts I needed from an old one and rebuild the current one.

Jig was installed on module to retain module side waterblocks.

Blank-off remove was commenced, however due to and large amount of water coming out of the line to have the blank-off removed work had to stop till the water evaporates.

Waterblock sealing surface cleaning and polishing will continue tomorrow.

Also, upon installing the jig a piece of fiberglass that had previously been manual inserted between two of the water lines (early to mid 2000's) fell out.

Fiberglass that fell out yesterday was put back in place (as well as possible).

Cleaning took place this morning with excellent results. Cleaning was performed with red scotch brite on the cleaning tool, air pressure at 40 psi while running, with one 60 second cycle. Three blocks (EE, HS and Window) needed a second pass to remove the indium.

Polishing commenced with 2000 grit wet sand paper. Paper was wet with isopropynol. 60 second cycles for double seal blocks, 30 second for singles. The 2000 grit pass was completed.

Polishing will finish tomorrow morning as well as removal of optics tray from source tray in preparartion for insertion of the source tray into the module tomorrow afternoon or Friday morning.
