A boat lined up with graphite and wrapped in 3 Ta heatshileds

Vacuum IGP1 initial = 6.76 e-7 Torr

Target temperature on OMEGA= 1800-1900 C

OMEGA slope:= 0.990

Target time at max temperature = 4 hours

Final TGHT current= ~420A (adjustable)

Heating autoramp started semi-manually on  TGHT  to 65A and then at continue to 100A

 1A/min  to =400 A TGHT

Good vacuum = 5.0 e-04 Torr

Bad vacuum = 5.0E-02 Torr

Set final value (A) to 400A

Set current increments (A) to 1A/min
