  1083   Friday, September 25, 2015, 08:21 Travis CaveSouth Hot-CellStandard Operation UC#13Spent Target move

The spent UC#13 target has been moved from the south hot cell to the ISAC spent target vault. It was placed pail #128 and in tray spot 1A. It was 21.5mSv/hr upon removal from the hot cell. See attached PDF for details.

David Wang and I did the service cap inspection in target hall: see WP I2015-10-06-10.<br>

Signs of sparking were seen underneath 3 insulators: E ("Cavity"), A ("Oven+") and B ("Oven -") at the pair water lines coming out of the  feed-through and going to the HV chase. Specifically one water line of E is very close to the feed-through insulator (2-3mm gap) and here the sparking sings are more prominent: see picture.

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.

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.

Rebuild handle of manipulator serial 7986 (currently in the east position) and replaced broken snap ring 5555-18h on west side of the handle underneath motion switch.

  1111   Wednesday, October 21, 2015, 11:58 Anders MjosSouth Hot-CellDevelopmentTM2ZrC#7Extraction 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).

Photos are available on DocuShare

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)

  1129   Tuesday, November 24, 2015, 13:54 chad fisherSouth Hot-CellRepair  Cell Decon

Decon/removal of large solid waste was performed on Wednesday November 18th."Hot" activated items included containment box cover from TM2, Febiad coil line remnants from TM4 (the hottest ends were previously cut off and disposed of), some target conductor bolts, steerer plugs from TM2, target material remn.

Drum containing these solid items is 2.5mSv/hr at 1/2m.

Drum is stored in the north hot cell temp.

Compressible waste will require another drum.

Swipes were taken of the window... 170k counts per minute of cont.

  1130   Tuesday, November 24, 2015, 14:00 chad fisherSouth Hot-CellRepair  Compressible waste sorting.

Residual fields from the remaining compressible waste were still too high (as far as I'm concerned) so I have unpacked all compressible waste looking for a "hot" item that has snuck into these items.

I have a hand full of small bolts (possible target components), a hand full of target material/dust (including an entire target disc), and some cloths that had clearly been used to wipe the table (they are black with target dust).

These items will be disposed of with the next spent target.
