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= N/A

Final TGHT current= ~400A (adjustable)

Heating autoramp starged at 4A/min on  TGHT  40A

Then at 2A/min on both heaters to 120A.

Good vacuum = 5.0 e-02 Torr

Bad vacuum = 5.0E-04 Torr

 IGP1 initial = 2.7e-07 Torr

OMEGA=1897C at 358A, 6.0V

Will ramp down at 230 pm


Thursday, November 17, 2022, 14:34

starting rampdown at -2A/min

OMEGA reads 1865C and IGP1=7.6e-07 Torr
