Argon venting TM2 at CS.

TM#2 with ZrC#7 has been moved from the conditioning station  to the west target station.

During last run， ITW dump circuit had a water leak on an adaptor below the pressure gauge. The top tank flange, slot, and O-ring were water contaminated by the leak. I removed the old o- ring, cleaned up the flange and o-ring slot, and put a new o-ring into the flange. Some  pictures will be attached in this mail later.

TM2 has been connected in ITW. During the connection, Anders and I  found the TM2  high current cables used in ITE and CS are short in ITW.  Anders and Grant found the original TM2 ITE high current cables in target hall. We replaced them. They works fine. But, a little bit longer on cable length would be easy to connect them. All other connections and HV cover in ITW work for the TM2 so far.

Maico and Dan moved 5 shielding blocks from ITE to ITW. The ITW is configured to take proton beam.

The corelation betwenn the local value on the gauge controllers and the read back valiues in EPICS was compared. Data can be found in a previous  e-log

Dan and I disconnected TM2 in ITW this morning.

Bill and I remotely removed TM2 from ITW to SHC. The move is smooth.

I did an electrical check on TM2 with ZrC #7 on it. The EE is short to 60KV bias. See attachment

ZrC#7 has been removed from TM2. Everything looks good.

I installed a set of new high current cables for TM2 Febiad run. The top of TM2  is configured to Febiad mode. See attachments

I did a TM2 no target electrical check at SHC this morning. A to RU at 500v  is 250K which is low.   anode- x pin is dead short to 60kv bias. RU is dead short to 60kv bias( as before).   see attachment

The TM2 containment box was removed this morning for installation of the 9 pin connector...connection.

The 9 pin connector copper tube connection was made and Anders advised on routing of the cable to the banana plug water block connection.

Short was diagnosed (short disappeared when water block was pushed slightly towards center of module) and thicker Ultem spacer installed and tested again. All good.

SiC#32 has been installed on TM2. High current fasteners torqued to 130 in lbs.

 An electrical check was completed by Travis C and Anders M. Note ~250 kOhm between Target and 60 kV common. Leak check was done by Dan M and Chad F on HS and Window circuits. No leaks found
