It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did not correspond to local values displayed on the controller. An e-fault has been submitted.

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.

TM4 has been connected in ITE. All turbo-pumps are started. Everything is good so far.

 After conditioning over the weekend the EE developed a short. This was confirmed by measuring the resistance between EE and Heat Shield on the module yesterday.

TM#4 with UC#14 has been moved from the conditioning station to the east target station.

I turned off TCS vacuum and water pumps. The TSC and TM4 are still under vacuum condition.

Weekly update TH schedule according to changes. see attachment 1,2 .

Update TH schedule before the weekend. see attachment 3,4

Ta#46 was placed in the ISAC spent target vault yesterday. See attached PDF for details.

TM4 has been connected at TCS. The water system is started. The TCS HV cover for TM4 is installed also. Basically, The TM4 is ready for conditioning.

I did helium pressure test on TM4 HS line at TCS this morning.  70psi helium 3 minutes, 0.0xE-9 atm.cc/sec base leak rate. No response. No leak.

TM4 vacuum has been connected in TCS. All vacuum pumps were started yesterday. The pumping down of TM4 and TCS are good so far.

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.

Cell (table) was systematically cleaned with a swiffer and resulting piles of contaminated waste placed in pail with spent Ta target.

UCx#14 installed onto TM4. High current fasteners torqued to 130 in lbs.

TM#4 with UC#14 was moved from the south hot cell to the conditioning station.  Here are the results of the electrical check of the module with the UC#14 target while at the hot cell.

Yesterday TM#4 with Ta#46 was moved from the east station to the south hot cell.

Ta#46 has been removed from TM4.

electronics package on left manip died completely yesterday (it has been going for a while).

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.
