Container coated with TaC using new method: Ends tapped off, with liquid poured in and swirled around entire container, then poured back out - 'flushing technique'
Container is wrapped with 3 x Ta heat shields, not incl center block.
Loaded into EVAP2 and currently pumping down.

IGP1 = 2.2e-6 Torr.
HS water valves opened.
No leaks detected.
Tapped up manually to 35A.
Vacuum stable.
Initiated auto ramp at 0.2A/min and 0.1A/min for the TGHT and TBHT respectively.
Final setpoints for TGHT = 720A and TBHT = 230A, with final desired temp of 1800C

IGP1 = 8.8e-7 Torr.
TGHT = 260A, 3.0V
TBHT = 145A, 1.8V
Increasing ramping rate to 2.0A/min and 1.0A/min for the TGHT and TBHT respectively.

IGP1 = 3.5e-6 Torr.
TGHT = 720A, 11.3V
TBHT = 230A, 3.2V
DV = 5.48V
OMEGA RS [right side-old port] = 1745C
OMEGA LS [left side-new port] = 1880C
Tapping up manually to achieve 1800C on OMEGA RS

IGP1 = 3.7e-6 Torr.
TGHT = 748A, 11.9V
DV = 5.78V
OMEGA RS = 1803C
OMEGA LS = 1935C

Remained at max setpoints for ~17hrs.
IGP1 = 1.3e-6 Torr.
DV = 5.79V
OMEGA RS = 1862 [this reading may not be correct due to the laser being moved at max setpoint - this temperature reading may be taken from a different location then the last reading]
OMEGA LS = 1955
Initiating auto-cool at 2.0A/min and 1.0A/min for the TGHT and TBHT respectively.
