Target boat with a layer of niobium foil on the bottom used to heat up Nb samples to 1100 C for 4 hrs.

OMEGA slope = 0.99

The niobium samples are wrapped in a layer of  Nb foil.

Boat is wrapped with 2 layers of Nb foil.

Good vacuum 3.00e-02 Torr

Bad vacuum 5.00e-02 Torr

Autoramping TGHT at 3A/min to 180A, then monitor until desired temperature (based on eLog 550)

Initial IGP1=9.9e-07 Torr
