Container was sprayed with TaC and let dry.
Container has 3x Ta heat shields including center block.
Container was loaded into EVAP2 yesterday and pumped down overnight.
HS water valves were opened up this morning, no leaks detected.
IGP1 = 4.6e-7 Torr.
Tapped up manually to 40A.
Waited ~25min, Vacuum stable.
IGP1 = 5.0e-7 Torr.
Initiating auto-ramp.
TGHT will be ramped to reach 2000C

Vented in air and opened up this morning.
Target container mostly sintered, two tiny patches near both ends not fully sintered.
Will re-install and re-sinter next week as another container with priority needs to be sintered first.
