TM1 shielding plates and their holding bolts are inspected. No corrosion.  TM1 is located at TCS now. Both TP1 and TP2 are started.

TM2 has been connected in ITE. high active water system and vacuum pumps are started. The pumping down on TM2 and ITE is good  so far.

See attachment for connection checklist.

 TM#1 has been moved from the north west silo to the conditioning station for the day it will be moved back to the silo tomorrow morning.

The following controls-related items were installed for the SMP project:

- Cable tray

- Main control panel

- Motor starter box

- Wiring from limit switches and rotation motor to main control panel

- Air fittings at supply (quick disconnect)

- Main air supply hose from supply to control panel (quick disconnect)

- Air tubing from lid control valve at control panel to lid cylinders

Air fittings stem off existing air supply lines on the South wall, below a manual shutoff valve. A quick disconnect was installed. When SMP is not in use, manual shutoff valve should be left off.

Main control panel and motor starter box were mounted on the North wall. Wire duct runs from the main control panel to the grated floor. Cabling/air runs underneath the mezzanine platform, along existing and new cable tray, to the SMP.

Cable tray was installed on the South wall, from the corner to the SMP module. A cutout was made to accommodate for existing tubing. An additional ~1 ft. of tray will be added to the end, near the corner, at a future time.

Remainder of installation work to be done before commissioning:

- Mount and install new Opto-22 module
- Chain new Opto-22 module to existing one (power, comms) below mezzanine on North wall

 TM#2 with Ta#58 has been moved from the south hot cell to the east target station.

 Results of the electrical check of TM#2 without target and with the new Ta#58 target.

Ta #58 has been installed onto TM2. All new silver plated high current fasteners. All torqued to 130 in lbs.

The SMP module support flange sub-assembly (IRH1755) was installed today according to drawing IRH1683.  Dow Corning 111 sealing compound was used to keep the o-ring adhered to the lower groove during transportation and installation.  The TCS shield plug (IRH1646) was then installed on the SMP module flange which has vacuum connections for leak checking.  Vacuum was pulled on the SMP vessel using the Varian 979 leak detector.  After approximately 3.5 hours of pumping the test port pressure was at 2.4E-2 Torr and leak rate was 7.9E-8atm*cc/s.  Helium was configured with the regulator set at 10psi and flow rate of >10 bubbles per second in Windex and then applied slowly around the perimeter of the vacuum flange (IRH1686) and it's mating components on both  the top and the bottom.  There was no response on the leak detector indicating the seals on both sides of the module flange are leak tight.

Entrance module has been connected back to ITW. Everything is normal.

 The West Entrance module has been moved from the south hot cell to the west target station.

West entrance module - visible broken or disconnected wire visible on old/existing wire scanner. Wire scanner removed, new one installed.

 The entrance module has been moved from the west station to the south hot cell.

 The spent UC#26 target was moved from the south hot cell to the spent target vault. It was place in pail #209 and put in spot 1A in the vault and was 2.42mSv/hr upon removal from the south hot cell.

 Electrical check of the TM#4 with no target attached at the south hot cell before being moved to the south west silo.

 TM#4 has now been moved to the south west silo.

UC#26 has been removed from TM4.

 Electrical check of TM#4 with UC#26 post beam at the south hot cell. See attached.

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

 The following targets have been moved from the spent target vault to the mini vault:

#127 - SiC#31 (front)

#132 - SiC#32 

#145 - UC#19

#150 - UC#20

#159 - UC#21 (back) 

Two pail transfers took place April 25th.

Ta#47 transfered from pail 137 to pail 201. existing plastic bag from 137 showed many areas of typical age/rad damage related failure.

Ta#45 in pail 124 was transfered to pail 202. Pail 124 also contained the shutter and "roof mounted" img gauge from TM2 that were removed in 2015 in addition to a bunch of fasteners, heat shrink tubing (from lock lever rings from an previous methods of spent target packaging) etc. The original plastic bag in pail 124 had completely failed and shredded and flaky. The shutter and extraction electrode from Ta#47 were put in pail 202 with Ta#45...cabling of the shutter being completely intertwined with the target.
