TM#4 with UC#17 is now in the conditioning station.

UCx#16 has been removed from TM$ and UCx#17 installed, high current conductors toqued to 130 in lbs.

UCx#16 did not show the standard arcing marks on the 9 pin connector.

In regards to the 9 pin connector on number 17, it was by far the best fitting TM4 target with 9 pin as it required no "fiddling" during installation.

TM#4 with UC#16 has been moved from the east station to the south hot cell. The shield plug was also install remotely once it was hooked up due to alphas.

 The North Hot Cell was accessed today via the Ante Room for inspection, measurements, and clean-up.  There were no modules in the SHC or TCS, and no spent targets in the SHC.  Under these conditions the maximum field in the NHC was approximately 2μSv/hr.  The inside of the cell was cleaned and swept, followed by a floor swipe to check for contamination (none found).  All areas of the ante room floor were also swiped:  no contamination found.

The following measurements were taken in the NHC for comparison with the Soldiworks model:

SHC/NHC feedthrough panel fastener size:  1/4"-20,  1/2" long
NHC west wall to east edge of SEG block:  33-1/4" on south side, 33" on north side
NHC west wall to furthest extent of TCS (IRH1170): 40"
NHC west wall to wall indentation for viewing window: 46-7/8"
NHC west wall to end of existing ventilation duct: 4-1/8"

TM#3 with no target has been moved from the conditioning station to the NE silo.

The two 45 gal (m) drums of waste removed from the south hot cell in December 2015 and January 2016 were transferred from the north hot cell to the shaft of the east vault tunnel on Monday, July 25th 2016 and subsequently to the east tunnel bunker in the vault tunnel on Tuesday, July 26th, 2016.The first drum (removed from the hot cell in December) containing both activated and contaminated metals was measured at 900 uSv/hr @ .5 m and the second drum (removed from the hot cell in January 2016) containing compressible items such as tank suits and plastic was measured at 150 uSv/hr @ .5 m.

Items were filed for storage/disposal with RPG under item number 1395 on the radioactive storage form.

Drums were transported to the vault tunnel using the 500 Mev Shield Flask (Drawing E-7097) with some minor modifications, namely a 1/4" thick Aluminum plate with four holes that line up with the holes in the bottom flange of the flask. This plate provided a bottom for the flask so that a drum could be contained within the flask during craning. Holes in the plate where countersunk for a 1/2" flat head bolt. Four bolts were also modified to accept 3/16 hair pins. 3 plates with clearances holes for the bolts were also manufactured to act as washers.

Procedure was as follows: With plate, washers and pins installed onto the flask, a modified drum dolly (5" spacers added to the casters) was placed inside the flask. Drum was craned into the flask using the automatic drum lifter. Flask with drum loaded was moved to the Meson Hall loading bay then craned to the B2 level of the Meson hall. Hair pins were pulled from the flask and the flask was then craned up leaving the drum (which was on the dolly firstly installed into the flask) and the plate. Drum on dolly was rolled to vault access shaft where it was craned off the modified dolly using the automatic drum lifter and down the access shaft to the vault tunnel level.  A second drum dolly was waiting at the bottom level and drum lowered onto it. Procedure was repeated for the second drum

Was vault was open , drums were wheeled into the vault tunnel and into a bunker that had been modified to accept these drums. Drums were lifted off dollies and put in place in bunker which had blocks installed to cover the entrance provided for installation.

I started vacuum system.

I started TCS water system. The chiller does not work properly still. But, It will not affect the TM3 HV conditioning.  HV cover is installed on TM3 in TH. The module is ready for HV conditioning.

Last Friday July-15, TM3 was leak checked at TCS. All air to vacuum seals on service cap are good.  Helium pressure test on  TM3 water lines(except GE, HS, and Window) were done. Leak detector has no response at 0.0xE-9 atm.cc/sec. They are leak free.

Friday July 15: did HV tests (with no target installed and with the anode wire removed ). <br>

TM3 went up to 22.5kV. At this voltage it started sparking. The EL was kept at 1/2 with respect to the HV BIAS. <br>

Also HV tests were done while the EL was kept at zero V. In this case, the EL voltage was once in a while spiking  up (up to 4kV). <br>

During sparking we saw responses in the vacuum. Checked the Service Cap (with the HV Cover) in the Target Hall: we couldn't hear/see sparks there.  <br>

The HV was turned off in the same day, after 5:30pm.

TM#3 is now in the south hot cell.

Update TH schedule 130 according to mini-shut down change.See attachment 1,2,3,4

TM#3 has been moved from the north east silo to the conditioning station.

Update schedule weekly.Attachment 1,2

All turbo-pumps are started. Everything is good so far.

TM#2 with SiC#33 has been moved from the conditioning station to the west target station.

The spent Ta#48 was moved from the south hot cell to the spent target vault. I was placed in pail 139 and is in spot 6C in the vault. It was 201mSv/hr when measured at the hot cell. See the attached PDF for the latest results.

I connected TM2 to TCS and started water system.
