Monday, August 17, 2015, 15:43: Reduced ANODE to 100 V

Monday, August 17, 2015, 16:56 : Increased EL to 8.3 kV to increase FC current.

Monday, August 17, 2015, 17:04 : FC0 current at 1.5E-8 A

Beam ionized and accelerated on the new TM2 source tray

Monday, August 17, 2015, 17:12 : TGHT / TBHT at 500 / 250 A. Will leave over night to outgas. ISAC ops are monitoring the source.

Tuesday, August 18, 2015, 08:07: Everything stable overnight. Continue ramping heaters.

Tuesday, August 18, 2015, 08:48: TBHT voltage limited by EPICS (hardcoded) at 273 A.

TGHT/TBHT at 600 / 273 A 

Tuesday, August 18, 2015, 09:52: Adjusted COIL current down to 0 and back up. Response seen on FC0.

Tuesday, August 18, 2015, 22:29 : Starting cool down.

 Wednesday, August 19, 2015, 08:26: Source and HV off. EE configured to conditioning mode. RGA off.

Wednesday, August 19, 2015, 08:42: BIAS/EL at 15 / 7.5 kV. PNG1 at 3.5E-6 T, IG1 at 3.9E-7 T

Wednesday, August 19, 2015, 08:53: BIAS/EL 20 / 10 kV. 2 sparks.

Wednesday, August 19, 2015, 09:54: BIAS/EL 30 / 15 kV. Some sparking around 28 kV required BIAS voltage to be reduced momentarily. 

Wednesday, August 19, 2015, 10:04: Sparking at 30 kV. Reduced BIAS to 13 kV to get spar rate to less than 10/min

Wednesday, August 19, 2015, 10:19 : BIAS current limiting. Switch off BIAS and EL

Wednesday, August 19, 2015, 12:04: Water off for purging and leak test.

Wednesday, August 19, 2015, 12:52: Vacuum response observed while David was working on purging the water lines. This turned out to be when the valve to the leak detector was opened.

I finished the rest TM2 connections to CS, and started CS cooling package. Everything works fine so far.

TM2 has been moved to CS. All turbo-pumps have been started. The pumping down is good so far.  I connected the leak detector to service cap, and finished the leak check today.  The LD base LR:0.0Xe-9atm.cc/sec. 80psi helium were applied to coil1, coil 2. HS and window circuits, each for 2minutes. No any response has been found on LD. So all water lines are leak tight now. I also sprayed   helium to top service cap checking all air to   vacuum seals. They are all good either. But, The new installed PGN1 does not work. Other thing need to mention is The TP2 is running at 2.45A which is 1A higher comparing to TP1. It need to be monitored to see if we have to replace it or not. The high current cables and water lines will be connected tomorrow morning.

TM#2 with the dummy target has been moved to the conditioning station.

As previously mentioned, dump target installed with new mounting and high current fasteners.

Leak Check complete and ready to move to CS at 1:30

Electrical check of TM2 without target after that widget has installed, electrical check with the shunts on, electrical check with the dummy target installed.

Tuesday, August 11,  insulator ITA6272 was installed onto the "pin x" line (unused plasma electrode) and tested; it seems to have successfully eliminated the shorts on that line.

Wednesday, August 12  "shunts" installed on tube heater and oven circuit and electrically  tested.

Thursday , August 13, dummy target installed.

The containment box was taken off TM2 in preparation for installation of a new coil line isolator.

ITA6272 and ITA6273 have been received from the Scintillator Shop.  ITA6274 should be ready by the end of today.

Weekly update target hall schedule and activities. See attachment 1,2

Update and extend Target Hall schedule to Sep 08.  See attachment 3,4

TM#2 is now in the south hot cell

All targets but one ( SiC#31 went in last week) have been measured or assayed. See attached PDF for the details.

Weekly update of Target Hall schedule after so many jobs have been finished in this week.  See attachment 1, 2

SiC#31 has been moved to the spent target vault. It is in pail #127 and placed in spot 3C of the vault is was 489mSv/hr when removed from the south hot cell. See attached pdf for vault status

Dan and I connected TM4 in ITE. We checked all water signals on ITE cooling circuits. Everything is good.

TM#4 with UC#13 has been moved from the conditioning station to the east target station.

Dan and I stopped the CS and TM4 pumps. We are venting the CS with argon for UCX13 target.

SiC#31 has been removed from TM4 and UCx#13 installed. UCx#13 connection to the 9 pin connector was VERY VERY tight to the tube heater insulator on both the test jig and module.

Extraction electrode was removed from SiC#31 and target inspected.

Pictures of findings can be found at          https://documents.triumf.ca/docushare/dsweb/View/Collection-15131

TM#4 with UC#13 electrical check at the conditioning station under vacuum. See attached PDF.

Tony and I replaced the ITE TP4 turbo pump today. The pumping time on controller has been reset to 0. The replaced broken  pump is bagged and stored at west end of TH.
