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.

Entry  Tuesday, November 22, 2011, 15:07, Bevan Moss, Conditioning Station, Standard Operation, TM1, UCx #3, HV testing UCx_#3_HV_testing.JPG

 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 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.

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.

Entry  Wednesday, November 16, 2011, 07:44, chad fisher, South Hot-Cell, Standard Operation, TM1, TaC#1, TaC#1 Removal and inspection 

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.

Entry  Thursday, November 10, 2011, 14:33, Travis Cave, Spent Target Vault, Standard Operation, , , Spent Target Assay 

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.

Entry  Wednesday, November 02, 2011, 13:12, Bevan Moss, Conditioning Station, Standard Operation, TM4, SiC#26 High Powered, High Voltage (HV) testing 

 The silicon carbide targets voltage was raised to 42 kV today before continuous current draw was observed. It took roughly 10 minutes to raise the module to this voltage with only the occasional spark. The ION gauge reading was 2.0 x 10^-6 T, The service cap IMG 3.6 x 10^-6 T, and the secondary vacuum was 4.5 x 10^-6 T. Setup check and conditioning was performed by Pierre.

Entry  Tuesday, November 01, 2011, 11:50, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 leak test on conditioning station 

 I did a leak check again on TM4 today. This time, the leak detector pump to the bottom on both base pressure(0.0xE-4 torr) and base leak rate(0.0xE-9 atm.cc/sec). All high vacuum gauges on TM4 and conditioning station at -6torr range.IG1 is 3.3-6torr,PNG5(top of service cap)is 6.5-6 torr, and the PNG4(bottom of the vessel )is 8.7-6torr. For air to vacuum leak checking, I checked the panel we moved last week on service cap by spraying helium around the panel. There is no any response on leak detector. The panel is leak tight. Also I sprayed helium around the tube heater (+) water cap and blue nylon stand. They are also leak tight. Then, I put 80 psi pressure air to the “D” circuit first. With 80 psi pressure air for 5 minutes, the leak detector has no any response on it. Also all high vacuum gauges stayed at same level .Then I checked it with 80 psi pressure helium for 3 minutes. The leak detector has a response on leak rate with pressure helium same as last time. It climbed from the 0.0xE-9 atm. cc/sec quickly to high -8 range then slow down. The leak rate finally climbed to 2.0 X E-7 atm.cc/sec this time. There is no base pressure change on leak detector. All high vacuum gauge readings no change during the test time. There is a small helium leak at 80 psi pressure test on “D” circuit. But we can not locate it at this stage. Also I don’t want to disturb this circuit any more before the febiad run since this time I saw a little bit increase on leak rate comparing to last time when I checked it. If we really like to find this small helium leak, I would suggest we do it after the febiad run.    Thank you.
