TM2 been connected with new target C#3 in ITW. 

 the test was done when TM2 sit on NHC.

 the module TM2 with target C#3 was disconnected at ITW and is being remoted moving to SHC.

 The spent C#3 target has been moved from the south hot cell to the spent target vault it was placed in pail #270 and put in spot 2C of the vault. See attached PDF for more details.

TM2 electrical check and leak check are done at SHC with C#2 target installed. The results are good.  

 TM#2 with C#2 has been moved from the south hot cell to the West Target Station.

C#2 has been moved from the south hot cell to the spent target vault. It is in spot 8A of the vault in pail # 235 and was 185 mSv/hr upon removal from the south hot cell.

The Target Index spreadsheet has been updated on DocuShare.

Target C#1 has been installed on TM4 with new high current fasteners torqued to 130in lbs.

Target to HS is 400 ohm. The rest check is good. See attachment.

Remotely remove TM2 from ITW to SHC. The move is good.  Shielding plug is put back to ITW.

SEE ATTACHMENTS. EVERYTHING IS GOOD.

Five shielding blocks are transferred to ITW

Pail 237 only has 200u sv/hr field at 0.5 meter. On contact measurement: 0.9 to 1.6 m sv/hr.and less than 80 count contamination outside the pail.   It is moved to mini storage. We will transfer this pail to cyclotron vault and store it there later.

PQ SHORT TO RU. A TO PQ 1.8 M OHM AT 500 V. THE REST ARE OL

The 2A3 window now has a lid, and lift yolk on it and it has been installed in the spent target vault in spot 2A. The lid is a normal unmodified and has no sealant on it.

The pail containing window was transferred from the Storage Vault to the Cyclotron Vault Tunnel Storage 2017 Mar 24. It was placed in a brick bunker along the north wall and marked with item #1434. RPG storage form is attached.

Highest field measured at 0.5 m was 3000 uSv/h with an estimate of 4000 uSv/h on contact with the pail. Pail exterior was not contaminated. See attached storage form for details.

 

2A window has been removed from the vault and moved over the cyclotron vault tunnels.  Attached is the updated storage vault list.

 The pumping down on TM1 and conditioning station is fine over the weed end. The PNG 1(containment box) is 2.4xe-6 Torr, the IG1 (top service cap) is 9.0 xE-7 Torr, and the IG4 is 1.9xE-6Torr (diagnostic box). At this pressure, I connected the leak detector to the system and applied 80psi helium to the heat shield circuit. The leak rate and base pressure on leak detector are 0.0xE-9 Atm.cc/sec and 0.0xE-4Torr. There is no any response on leak detector during 4mins helium applying time. So the heat shield and Nb5 target water circuit is completely leak tight.

TM1 has been reconnected in ITW. Water interlock check for TM1 is done.

The target module has been moved to the Conditioning Station (CS)

Pumping overnight

Saturday June 25 2011

Pressure Service Cap (SC) 3E-6 T

Pressure Containment Box (CB) 6.6E-6 T

High voltage test to 40 kV, unfortunately, the pressure is not great so we stop at 40 kV

Pressure at the end of the day: 1650H was, P SC 2.6E-6T

P CB 6.6E-6 T

Sunday June 26 2011

Pressure P SC 1.6E-6T

P CB 6.6E-6 T

It seems we have a leak. The pressure does not drop in the CB over one day.

Today June 27 2011

 Pressure P SC 1.2E-6T

P CB 6.6E-6 T

We leak check the target module and found two leaks, one on the ground electrode and one on the mounting plate cooling circuit.

This is a new one. We had test this line three times before and it was ok.

Action for tomorrow.

After CS vent, 

Move TM1 to SHC

Survey 

Connect LD to Mounting plate cooling circuit

Open Side panel and leak check.

Meeting at 0830H
