Tapping up manually to 1900C.    Monday, November 09, 2015, 12:30 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...

Heat treatment of 2 bullet-shaped Nb samples in a LP-SIS container; it is just that we don't have a target boat. 

Container is wrapped with 12" in total length.  A strip of Nb foil is used as an underlayer for the samples to sit on top. 

Chamber has been pumped down and current vacuum at 1e-6 Torr. 

HS water check - good.

Target temperature 1400C

Ramping up to 250A; this should get to ~1300C.  Will let it heat for over night and step up to 1400C tomorrow. 

 Wednesday, February 24, 2016, 17:59

I'm stopping the heating process because the camera is not working.  I can't monitor the temperature.  Tried to fit the camera; don't now why it fails to connect to the server. 

Will look in to it tomorrow...

 Thursday, February 25, 2016, 08:17

Initiated auto ramping TGHT at 2A/min.

Thursday, February 25, 2016, 17:33

Current temperature is at 1126C, TGHT at 250A.  Will step up to reach 1400C. 

Thursday, February 25, 2016, 18:04

One thermocouple was not welded on correctly and is not working. 

Cooling evap2 back down, to remove target and re-weld thermocouple.

Once thermocouple replaced, will ramp back up and continue with tests/ conditioning of target.

 After EVAP2 was vented the thermocouple problem was fixed: it was the wire at on connector inside the box not making proper contact. The lid of the heat shield was also replaced since the one initially mounted had no holes, so one couldn't see the center block. Restarted pumping down at 4:30pm. Just started again the autoramp program: TGHT set to 300A (for the time being) and TBHT to 230A. Temperature measurements will resume tomorrow morning.

 Raised the TGHT at 620A. The TBHT was already set at 230A. The temperature is at 1902 deg C. As per John's instructions the target will condition at these setpoints over the week-end.

With the ionizer tube facing into the page, the bend appears to be in the center with both ends of the container bent slightly towards the page

This possible bend in the container gives the appearance of the oval shape through the camera while it is being heated, due to the angle of the camera
