TGHT has been at 520A/9.80V, DV 5.80V for 7 hours, temperature measured at 1800C. Vac is coming down to 9.18e-6 Torr. However, TGHT voltage is slightly going up over the 7 hours of heating, See screenshot attachment. (Can't make further comments until target is inspected.)
Initiated cooling down at 2A/min for TGHT and 1A/min for TBHT.
Chamber can be vented later today.
Monday, June 29, 2015, 14:58
Target has been inspected.
Slightly crystallization on the outer tube of the container can be observed.
Overall, the container looks a lot better than before.

After almost an hour at 870A, the temperature went up from 1948C to 1980C; however temperature around the target container/legs are >2000C. The voltage on the power supply also went up slightly.
There is a film coated on the window port and that could affect the temp reading.
To be safe, I lowered the TGHT to 830A/17.38V, temp at 1930C.
Will keep at 830A for 4 hours and cool down this evening.
Recommend: Using Ta-heat shields for sintering next time.

Chamber was vented and the target was inspected.
Some stressed marks on the target container can be observed.
The container is also slightly curved but otherwise it's fine.
The materials packed length has expended outward so 3 discs were removed in order to insert the end caps.
The packed length is now 16cm.
Two extra graphite foils were inserted on both ends, and previously coated/sintered TaC-end caps are inserted and expended.
Rn foil is inserted & Std solutions are added.
Ready for test-stand.

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

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...

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.

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

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.

Springs coated with TaC and loaded into container for sintering.
3x Ta heat shield.
EVAP2 currently pumping down.
Friday, November 06, 2015, 08:39
Opened HS water valves, no leaks detected.
Tapped up manually to 35A.
IGP1 = 5.5e-7 Torr.
Friday, November 06, 2015, 10:08
IGP1 = 5.8e-7 Torr.
Vacuum stable.
Initiating auto-ramp at 0.2A/min and 0.1A/min with final setpoints of 450A and 230A for the TGHT and TBHT respectively.
See photos attached to view how springs were coated and loaded into container.

Checked the temp on the inner surface (not at the spring) of the container was around 2050C at 500A.
The TaC coated spring is reading at 1900C; that's what the OMEGA is reading with the setting for 2-colors and slope at 0.98.
Lower TGHT to 450A/ 7.12V.
By comparing the data from the previous temp curve (OMEGA slope at 0.98) with no material inside the container, the voltage and current plot is aligned with the curve.
Changed OMEGA setting slope to 1.04. Current temp is reading at 1917C at 450A.
For 2-Color setting, the emissivity should be negligible. That makes me believe that different materials has different slope setting for the temp reading.
One thing to note is that, the sintering temp of TaC is around 1900-2000C. It was clear that the container was fully sintered with TGHT at 450A.
Will need to gather more data with different material to understand the slope setting better.
Try:
SiC at 1700C, slope at 1.04
ZrC at 1900C, slope at 104
Ta at 1900C, slope at 0.98.
Compare the data...
