TGHT will be ramped up to 580A at 0.2A/min
TBHT will be ramped up to 230A at 0.2A/min.
Chamber has been pumped down. HS cooling H2O valves are opened, and no leaks are detected.
Currently IGP1 @ 5.9e-6 Torr.

The container was heated up to 580A TGHT/ 230A TBHT for a day (see attachment #1 for vac vs cur plot).
The temperature was measure at ~1780C. (see link for details: https://www.dropbox.com/sh/d8d9j2t60qlm3jk/nkMh7dx_R8 )
The target was cooled down and vented.
Proceed complete.
