Friday, November 06, 2015, 14:35: Roughing
Turbos was started around 4pm. Later it was found that the manual valve for the two turbo pumps on the service cap was closed. The valve was open and pumping resumed. The roughing vacuum was high and increased into Saturday morning. The vacuum system was switched off on Saturday.
Purged MP1 using the purging function. Performance recovered. Started rouging.

Monday, November 09, 2015, 16:47, Anders Mjos, Conditioning Station, Maintenance, TM3, FEBIAD Test Target, Leak check of Service Cap
|
Service cap leak checked this afternoon. Found multiple leaks of 10E-8 to 10E-7 range. Connected to the backing line with IG1 at ~4E-6 T, CG1A around 40 mT. Got responses around large round flange on top, rectangular side panels, water f/t on GND and water f/t on HV. Will resume leak checking tomorrow to attempt to pinpoint sources of leak more accurately. |

|
Five F-308s have been filled with the spent targets. The F-308s have been moved to the hall way between the north and south hot cell areas. |
|
Friday, October 23, 2015, 11:40, Travis Cave, Spent Target Vault, Standard Operation, , ZrC #7, Spent target moved
|
The spent ZrC#7 target has been moved from the south hot cell to the spent target vault. The target was placed in pail #129 and then placed in slot 3B of the vault, it was 157mSv/hr upon removal from the south hot cell. |

Friday, October 23, 2015, 11:30, chad fisher, South Hot-Cell, Standard Operation, , ZrC#7, ZrC#7 Spent Move and Febiad Coil
|
ZrC#7 was transfered to a spent target disposal pail today and removed from the hot cell. The "hot" end of the TM4 coil end was also disposed of in the same pail (#129) |
|
Friday, October 23, 2015, 07:41, Dan McDonald, Spent Target Vault, Maintenance, , , F-308's
|
Six F-308's where received from Nordion #6,#15,#13,#16 all contained contamination. Loose contamination was removed with some fixed contamination remaining levels are low enough to allow the transport of spent targets. flasks where serviced as per Nordion Document IS/PP 0009 F308, IS/PP 0981 F308. Flasks are now located in the north hot cell area. |

Wednesday, October 21, 2015, 11:58, Anders Mjos, South Hot-Cell, Development, TM2, ZrC#7, Extraction Electrode inspection
|
The failed extraction electrode was inspected in the hot cell this morning by Anders and Chad. The following electrical measurements were taken
- EE on target assembly as recieved from TM after online operation. 14 Ohm
- EE removed from target assembly and placed on conductive flat surface. ~1 G-Ohm at 1kV
- EE installed back onto target assembly (fasteners not tightened).~ 0.8 G-Ohm at 1 kV
There was some material deposited on the EE. Some of which has fallen off - possibly during removal of the electrode from the target assembly. It seems the cause of the short was material build up between plasma electrode and extraction electrode. See photos.
The heat shield lid was removed after lunch. This revealed a broken target. The target may have broken after operation (in hot cell).

|
The febiad coil line removed from TM4 has been cut into pieces small enough to be disposed of in a 5 gal pal. The line was cut with a Ridgid Model 104 manual pipe cutter (using the manipulators of course).
This pieces constitute the bulk of the field in the hot cell and will be disposed of with the next spent target. |

Thursday, October 15, 2015, 14:17, chad fisher, South Hot-Cell, Repair, TM2, , Anode Connector Install and adjustment
|
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. |
