The coated container was wrapped in four Ta foil heatshields.

Target temperature on OMEGA= 1850-1900 C

OMEGA slope:= 0.990

Target time at max temperature = 4 hours

Final Current TBHT= 230A

Final TGHT current= ~400A (adjustable)

Heating autoramp starged at 4A/min on both TGHT and TBHT to 40A

Then at 1A/min on both heaters to 120A.

Good vacuum = 5.0 e-02 Torr

Bad vacuum = 5.0E-04 Torr

 IGP1 initial = 2.8e-07 Torr
