Container coated with TaC using 'flushing technique' [cleaned ionizer tube with acetone, so no coating inside ionizer tube]

Wrapped with 2 x Ta heat shields - one full height of Ta foil wrapped around cooling fins twice

Currently pumping down in evap2

Tapped up manually to 40A

IGP1 = 6.6e-7 Torr

Initiating auto-ramp at 0.2A/min and 0.1A/min for the TGHT and TBHT respectively.

Final setpoints for TGHT = 650A and TBHT = 230A

Once max setpoints reached will continue to tap up manually while monitoring temperature to 1900C
