Manually changed current from 500 to 615 A, monitoring the temperature. Temperature went from 1657 C up to 1838 C. Pressure increased up to 7.2e-7 T.
Samples should be left for about 4 hours (615 A started just before 13:00), then the goal is to ramp current back to zero. |

Target boat is filled with Ta-coated endcaps. The caps are stacked together. In between each cap, a piece of graphite foil is used
for separation so the Ta caps would not fused. |
