I did a vacuum leak check on all ITE primary vacuum vessel and secondary vessel.I also did a helium pressure test(80psi ) on all TM4 water lines. There is no leak has been found.ITE and TM4 are both leak tight now.

ITE primary vacuum vessel and TM4 waterlines:

Hooked leak detector after TP1 between BV1. leak detector base pressure :0.0xe-4 torr. base leak rate:1.8x e-8 atm.cc/sec.sprayed helium around all TM4 and exit 1 ,2 module primary vessel including all flanges,  gauges, bellows,turbos,blank offs,etcThere is no  any response  on leak detector. All water lines  had been pressurized with 80 psi helium  for 5 minutes. The leak rate always stayed at 1.8xe-8 atm.cc/sec which is the base leak rate  on ITE this time, and no vacuum pressure change also.The TM4  water lines and ITE primary vacuum vessel are leak tight.

ITE secondary vacuum vessel:

Hooked leak detector after TP1S between BV1S. Leak detector base pressure :0.0xe-4 torr.Base leak rate:0.0xe-9 atm.cc/sec. Sprayed helium around all TM4,EXIt 1,2  module secondary vessel including alll flanges,gauges, air cylinders , valves, and blank-offs.There is no any response on leak detector . tThe late rate  kept at 0.0XE-9 ATM.CC/SEC, and no pressure change either.The ITE secondary vacuum vessel is leak tight.

Looks like the UC target s #1 and #2 were found invalidprize winners for their all inclusive trip to Chalk River and have thus been placed back in to storage for the next draw. In their place a pair of lucky Ta targets won, seems to be Ta lucky draw this year, Ta#28 and #29 have been placed in the mini storage for several fabulous day and wondrous nights, before being whisked away on their all inclusive one way trip to Chalk River. See attachments for the status of both vaults.

Well the first of this year's lucky winners to win a fabulous one way trip to Chalk River are as follows. UC#1, UC#2, Ta#25, Ta#26, and Ta#37. First these lucky winners will get to stay several days and night in the lovely all inclusive mini vault before being loaded in to their very own private F-308 flasks to be whisked away off to fabulous Chalk River.

Spent target assay completed. A total of 16 target were looked at, 13 were low enough to be assayed and those 13 are at shippable levels, the other 3 of the 16 looked at were too hot to ship and assay. See attached pdf for complete details.

TM#1 with UCx#3 moved from the conditioning station to the west target station.

TM#1 with UCx#3 moved from conditioning station to west target station. Move went well.

 High Voltage (HV) testing was completed on TM1 today. Vacuum was very good 1.9 x 10^-7 T in the service cap, 3.2 x 10^-7 in the containment box, and 2.0 x 10^-6 in the secondary. The voltage was successfully brought up to 27kV with a current draw of 0.12mA and o sparking. At the next step, 30 kV, the current draw was above 0.3mA and sparking was beyond 20 sparks per minute. The module should not be taken above 27kV. There is the possibility this voltage can be increased with conditioning but it is very unlikely. See attached for a graph of the testing. These results are comparable to the results without the source tray (see previous elog)

TM1 full leak check in conditioning station has been fulfilled this morning.Both air to vacuum leak check and waterlines helium 80psi pressure test are fine.The result:

Air to vacuum helium spray:base leak rate on leak detector 1.6x E-9 atm .cc/sec.base pressure0.0xE-4 torr. sprayed helium around all flanges, turbo pumps,panels,bellow,insulation stands, gauges. No Response on leak detector. Air to vacuum seals on TM1 is leak tight.

The base pressure on leak detector stayed at 0.0x E-9 torr through all the test, and no pressure response on high vacuum gauges.

 TM1 was high voltage tested without a target on November 16, 2011 with Don Jackson, Pierre Bricault, and Bevan Moss. The module was able to hold up to 25 kV but between that and 32 kV there was lots of discharge which could be measured in the vacuum. See the attached plot for the voltage current and sparks.

TM#1 with UCx#3 has been moved from the south hot cell to the conditioning station. Move went well.

UCx#3 has been installed on TM1.

Leak check also complete.

Base Leak Rate 0.0 x 10-9

Pressure 0.0x10-4

Two checks on upper heat shield joint - no response (2 sec spray/check)

Two checks on lower heat shield joint - no response(2 sec spray /check)

10 sec flood of all heat shield joints - no response

Electrical check coomplete.

Electrical checks of TM#1 with UCx#3 have been completed. They all appear to be with in operational range. All megger checks were done at 500 volts. See attached file for details.

TM#1 moved from the conditioning station to the south hot cell. Move went well.

TaC#1 was moved from the south hot cell to the storage vault. It was placed in pail#92 and put in vault slot 7B. It was 239mSv/hr upon removal from the south hot cell.

Inspection of TaC#1 showed that the oven was indeed broken on the A+ (left oven leg) side of the central block.

See the following for pictures.

November 15, 2011 removed TaC#1 from TM1 and inspected TM1 for any obivous signs of trouble (Problems with EE at end of run).

Upon starting removal of the high current conductor fastener on A+ (Left oven leg) it became clear right away that the oven of the target was broken as the leg moved as soon as the fasten was loosened.

Inspection of TM1 with the target removed yeilded no obvious signs of trouble, save a piece of capton tape found on the sliding tray directly below the service tray.

TM#1 has been moved from the south hot cell to the conditioning station. Move went well.

TM#1 with TaC#1 from the west target station to the south hot cell. Move went well.

For the week of November 7th 2011, four of a possible ten targets that are in storage were assayed. Targets are as follows:

Target             General average field @ 1 metre from edge of pail

SiC#24           1.99 mSv/hr

Nb#4               3.89 mSv/hr

Ta#25              4.57 mSv/hr

Ta#37              0.47 mSv/hr

These four are all viable spent targets to be shipped. We still need another couple of days of "UNINTERRUPTED" time to assay the remaining six targets, for us to have enough to make a ship of five to Chalk River.

TM#4 with SiC#26 HP move from the conditioning station to the East Target Station, move went well.
