Another drum of waste was removed from the south hot cell this morning. This drum contained one 5 gal steel pail (damaged), two sodium light bulbs, airlines, and tank suits. Upon removal the drum was/is 1.5 mSv/h on contact. there was 200 counts of contamination found on the lid...easily removed. It will be moved to the north hot cell at 11am.

Thursday, November 26, 2015, 09:55: PS energized. EE connected to power supply.

Thursday, November 26, 2015, 11:41: Applied some current and voltage to all power supplies. All looks good.

Some sparking around 5 kV. Turned out to be a bad cable connection. Fixed with David W.

Thursday, November 26, 2015, 15:04: BIAS/EL/EE 20 / 15 1.5 kV

Thursday, November 26, 2015, 15:43: Handed TCS over to ISAC operations


 Target heated over the weekend. EE went into current limiting (down to ~100 V) a while after the target was at temperature.


Monday, November 30, 2015

Target conditioned by ISAC operators to 30 kV without any problems.

EE current limit increased to about 26 mA in an attempt to recover. Cooling down target to investigate.

Disconnected entire package and replaced with package from "spare" manipulator.

everything is back up and working.

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.

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.
