The coated container was wrapped in 3 Ta foil heatshields.

Target temperature on OMEGA= 1850-1900 C

OMEGA slope:= 0.990

Target time at max temperature = 4 hours

Final Current TBHT= 230 A

Final TGHT current= ~500A (adjustable)

Heating autoramp starged at 1A/min on  TGHT  and TBHT to 120A

Then at 2 A/min  to =400 A TGHT and 230A TBHT

Good vacuum = 5.0 e-04 Torr

Bad vacuum = 5.0E-02 Torr

Initial IGP1= 7.7e-07 Torr
