Tantalum samples were loaded in a tantalum testing tube and installed in the EVAP2 to heat under vacuum for 3 days at 2000 degC (~500A, 4kW).
The temperature is measured with the Omega pyrometer (slope 0.98)
Some of the samples are in contact with graphite and enclosed with Ta caps, the other samples are not in contact with carbon.
The testing tube is wrapped with 3 Ta heat shields and is not TaC coated.

Yesterday, Wednesday June 08, 2022 @ ~3.00 pm a "dummy" target container was installed in EVAP 2 after the heatshield assembly had been swapped.
The purpose is to test correct functioning of the system. Melting and evaporation on one of the bolts of the previous target container (eLog578) prompted the change in heatshield assembly and current testing.
TGHT was ramped up to 740A @ 4A/min, left to run at the final current for ~4.5 hours and then ramped down @-2A/min to 0A.
Will dismount dummy container this morning.
