IGP1 = 6.5e-7Torr
HS water valves opened, no leaks detected.
Tapped up manually to 35A.
Waited ~20min.
Vacuum stable, IGP1 = 1.5e-6 Torr.
Initiated auto-ramp at 0.2A/min and 0.1A/min for the TGHT and TBHT respectively with final setpoints of 250A and 230A.
Final temp of 1200C on auto-ramp in order to initiate temperature measurements starting at ~1200C.

IGP1 = 8.7e-7 Torr
TGHT = 44A, TBHT = 38A
Increasing auto-ramp to 0.5A/min and 0.2A/min for the TGHT and TBHT respectively.

A few notes about the target container:The Ta-foil is cut in a full length of the target container, and that also covers up the back block, and the container is wrapped with 3 sheets (see attachment)
The inner tube is coated with TaC, using the "flushing technique" - the coating looks much better; will see how it turns out after the sintering process
The target will be heated up to 1900C . Due to the new wrapping of the Ta-heat shield, the heat distribution may be different. So the target heater will be ramped up to achieve the desired temperature.
Thursday, September 24, 2015, 18:45
TGHT reached to 250A3.6V, TGHT at 230A and stayed for 1.5 hours. Temp-L = 1280C, Temp-R = 1360C.
Auto-ramp TGHT to 500A at 1A/min and heat at that current for overnight. Will take temp reading tomorrow.
Thursday, September 24, 2015, 23:08
TGHT has reached to 500A/8.57V. Temp-L = 1895C, Temp-R = 2073C. (Not sure why the temperature is real, will need to investigate more to get an absolute temp)
Just to be safe… Ramping down TGHT to 425A (according to e-log id 216, Temp-R reached to 1800C with TGHT at 425A/6.84V, but no temp measured for the left at that time)
Will check again later.
Friday, September 25, 2015, 11:52
The target has been heated at 420A for ~12hours; temp measured ~1900C, slightly higher than the previous target container (W.O#40860-1); the Ta-wraping could affect the heat distribution.
The temperature is also confirmed by using the 2-C digital pyrometer. The tube inner surface is measured about 1900C, and the ionizer tube is about 2400C. (see attachment #2).
Initiating auto-cooling at 2A/min for TGHT and 1A/min for TBHT.
The target will be inspected next Monday
Wednesday, September 30, 2015, 16:01
The target container is fully sintered (see attachment#3)
It is still in the discussion where this container will be used online for the UCx. Nevertheless, the target contain is ready and it looks pretty good.

After further discussion, we are going to reheat this container to 420A. The temperature will be measured with the thermocouple - probe inside the centre of the tube - and the 2C-IR for comparison.
This test is to ensure that the container is actually heated to 1900C before the UCx material can be loaded
The chamber has been pumped down to 1.92e-6 Torr. Heat shield valve is open and no leaks are detected.
Ramping up TBHT to 230A max and TGHT to achieve ~1900C
Wednesday, October 07, 2015, 11:12
Yesterday...
TBHT ramped up to 230A and TGHT was at 160A before taking temperature readings.
TGHT from 160A to 423A, IR2C temp reading increases linearly from 1138C to 1900C, whereas the thermocouple readouts are not quite linear, 1040C to 1748C (see attachment)
After 18 hours, both temp reader dropped about 45C.
Increased TGHT to 440C, IR2C & thermocouple currently read 1912C & 1762C, respectively.
Wednesday, October 07, 2015, 12:28
Lowered TBHT to 200A and TGHT remained at 440A. IR2C = 1900C, TypeC = 1745C. Not much affect from TBHT.
Will increase TBHT back to 230A, then start ramping down TGHT and taking temp readings.
Wednesday, October 07, 2015, 17:49
Stepped down TGHT to 160A and TBHT stayed at 230A. Cooling down temp is generated. See attachment.
Notice the overall temp during cooling is lower than that during heating.
TGHT and TBHT will be ramped down to 0A.
Chamber will be vented tomorrow.
More details later...

Test 2: To heat the target container back to ~440A and measure the temperature with the type C thermocouple (inside the tube, away from the centre block) and compared the temp reading with the 2C-IR.
Chamber is currently being pump down, vac at 9e-6 Torr.
Will ramp up TGHT to 160A and TBHT to 230A at 2A/min.
Thursday, October 08, 2015, 17:01
TGHT is now at 440A, TBHT is constant at 230A - IR2C is reading the same as before, 1910C, but Type C is reading lower at 1770C. (see attachment)
Will keep the current at 440A overnight.
Friday, October 09, 2015, 10:06
TGHT has stayed at 440A, TBHT at 230A for ~18hours. R-temp dropped slightly from 1910C to 1890C and typeC dropped from 1770 to 1756; otherwise the measurements are reproducible.
After the group discussion, the online heating curve will be re-calculated based on the temp reading from the IR2C curve.
Next, the target container will be filled with UCx material and the conditioning current for Evap#1 will only go up to 440A (or at least the required current to reach the end of the re-carbonization step).
So pay attention to the current when heating the target up in EVAP#1.
Initiate cooling at 2A/min for TGHT and 1A/min TBHT
Friday, October 09, 2015, 11:35
A note about the voltage that may explain the change in the temperature:
See attachment #2:
Left plot = Test #1:
Initially TGHT ramped up to 423A and temp measured at 1900C. Notice, about an hour later, there was a sudden drop in the voltage, and from thereon, the temp was measured at 1860C. About 18 hours later, TGHT was increased to 440A to achieve 1910C.
Right plot = Test #2
Ramped up TGHT to 440A, temp measured 1910C. At that constant current over the 6 hours period, the voltage slowly increased, and the temperature slightly dropped to 1895C.

Laura Lambert | Empty | 39530-9 | HP-FEBIAD | Done | emissivity measurements with no h.s on HP-FEBIAD container - round2 | Monday, December 07, 2015, 09:04
No heat shields.
Container empty.
IGP1 = 1.1e-7 Torr.
Slope of OMEGA = 0.98
Tapped up manually to 35A.
Vacuum stable, initiating auto-ramp at 2.0A/min and 1.0A/min for the TGHT and TBHT respectively.
Final setpoints: TBHT = 90A, TGHT = 360A
Will tap up with the same parameters as last round to confirm results.
Friday, December 11, 2015, 11:44
Took out of evap2 yesterday.
Aurelia took many emissivity measurements to compare with previous data - which matched up.
The dip in emissivity before going up again around ~560A could be due to oxidation of the materials.

Turbo pump broken 
Currently being replaced...
Friday, July 15, 2016, 17:04
Turns out its not the turbo pump...TP controls and pump replaced, problem still happening.
Took out heat shield and used a closed loop to rule out leak in chamber, emptied all water lines - turbo pump now on.
Took v.long time to pump down. TP will remain on over wknd.
BP turns on, PV1 turns on, RV turns on - then takes very long time for vacuum to drop ~45min? before BV and TP can be turned on.
Possibly problem with threads on heat shield and not creating proper seal?
Will continue monday with evap2 mystery problem solving...
Monday, July 18, 2016, 16:14
Replaced heat shield and copper seals.
Container re-loaded.
Turbo pump on and good vacuum achieved! YAY!
Finished pumping down, opened HS water valves - no leaks detected.
Tapped up manually to 35A

Initiating auto ramp for TGHT @ 0.2A/min to a max setpoint of 400A

MORE problems with evap2 
TGHT reads 460A, 5.1V, 1170C - a lot of power is being lost somewhere...
Comparison from elog i.d. 291 [the last IGLIS container sintering of TaC coating] the TGHT read 460A, 7.5V, 1900C
Another problem: the read out on the power supply and read out on epics of the TBHT reads 215A; however, the 'current set' says 177A - two very different numbers?!
Ramping down evap2 at 2.0A/min and 1.0A/min for the TGHT and TBHT respectively to further inspect chamber and hopefully solve this...
Wednesday, July 20, 2016, 13:34
Chamber was vented in air and opened up for inspecting.
Fixed!
One of the steel plates used to stop reflection onto the door of the chamber was inserted improperly, resting on top of the 2 negative copper lines to the target leg, this was causing a short.
There was also a short from the right target leg touching the copper heat shield, the heat shield has been shaved down and corrected. It is no longer touching.
There were also 2 brackets that had fallen behind evap2 inside the cage, one was touching the positive lines - it wasn't quite touching the ground, but may have grounded it, causing another possible short.
The chamber was pumped back down and the HS water valves re-opened. No leaks detected.
Evap2 was tapped up manually to 35A.
Vacuum stable = 1.0e-6 Torr.
Initiating auto-ramp at 2.0A/min and 1.0A/min for the TGHT and TBHT respectively.
Final setpoints are TGHT = 400A and TBHT = 230A

Friday, July 22, 2016, 16:18
Container has remained at ~1900C for ~31hrs
TGHT reached 405A/1900C - then after ~23hrs dropped in temperature down to 1895C so was tapped up further to 410A/1910C for another ~8hrs.
TGHT = 410A, 6.57V
IGP1 = 3.1e-7 Torr
TBHT = 230A, 2.9V
