A TaC coated target container  was loaded with a graphite cartridge with UCx

The target container has 3 heat shields

EVAP1 pumping down

IGP1 = 2.09e-6 Torr

Good vacuum 5e-5 Torr

Bad vacuum 8e-5 Torr

Autoramp set up to:

TGHT= 1 A/min to 465 A (same current used to reach 1865 C in evap2 when sintering TaC coating - e-log 464 evap2)

TBHT= 1 A/min 230 A

After approximately 4 hours at maximum temperature the pressure was 5.85e-6 Torr and the autoramp was set to:

TGHT -1 A/min

TBHT -0.5 A/min

After 4 hours that the current stayed at 0 A, EVAP1 was vented with argon and the target was removed; before transferring the target to the preparatory glove box, the tantalum cap to collect deposits from the target was inspected, there was not deposits on it so it was determined that the conditioning was successful and the target was transferred to the preparatory glove box.
