Weekly update of Target Hall schedule after so many jobs have been finished in this week.  See attachment 1, 2

SiC#31 has been moved to the spent target vault. It is in pail #127 and placed in spot 3C of the vault is was 489mSv/hr when removed from the south hot cell. See attached pdf for vault status

Dan and I connected TM4 in ITE. We checked all water signals on ITE cooling circuits. Everything is good.

TM#4 with UC#13 has been moved from the conditioning station to the east target station.

Dan and I stopped the CS and TM4 pumps. We are venting the CS with argon for UCX13 target.

SiC#31 has been removed from TM4 and UCx#13 installed. UCx#13 connection to the 9 pin connector was VERY VERY tight to the tube heater insulator on both the test jig and module.

Extraction electrode was removed from SiC#31 and target inspected.

Pictures of findings can be found at          https://documents.triumf.ca/docushare/dsweb/View/Collection-15131

TM#4 with UC#13 electrical check at the conditioning station under vacuum. See attached PDF.

Tony and I replaced the ITE TP4 turbo pump today. The pumping time on controller has been reset to 0. The replaced broken  pump is bagged and stored at west end of TH.

I did the helium pressure test on TM4 HS line at CS. Applied 70 psi helium  2 minutes. base leak rate0.0x E-9 atm.cc/sec.  No response during the test. No leak.

I connected the CS  vacuum system  to TM4. The CS and TM4 turbo pumps are started. Everything is good so far. The HS line will be pressured with helium tomorrow for leak checking. The CS and TM4 will be vented with Argon on Wednesday morning as planned before moved to ITE.

The yellow steel plug is put on SHC in TH. The spent target is inside the SHC.The field around the SHC area in TH is so high that we have put it on. It will be moved out on this Thursday just before the spent target move. 

Chad and I leak checked the HS line at SHC after UCX target installation. On first round helium spray, one of VCR fitting has a leak to E-6 atm.cc/sec range. Chad tightened the fitting, and solved the problem. We leak checked both VCR fittings twice. No leak. The line will be helium pressured at CS tomorrow.

TM#4 has been moved from the east target station (morning with SiC#31), and moved to the conditioning station from the south hot cell with UC#13 on it.

Electrical check of TM#4 with UC#13 at the south hot cell. See PDF for details.

Electrical check of TM#4 post beam with target (SiC#31) on and module without target on. There is a short between the target and EE when the target is on and when the target was removed short went away. See the PDF for details.

TM#2 has been moved from the south hot cell to north east silo.

Dan and I moved 5 shielding blocks from ITE to block storage area. The move is smooth.

Update Target Hall schedule after the changing on TM2 process. See attachment 1,2

Pin X was unplugged, short remained, however any slight pressure on the block towards the source tray makes the short go away.

Confirmed clearance between the EE and thr R / U coil lines as well as MSP of coil line.

Camera inspection would seem to indicate that ALL issues stem from a common location...there is a spot where both the pin X waterline and the one of the R / U waterline  contact the heat shield waterline...one on one side of the heat shield line and the other on the other side.
