HS water valves opened this morning, no leaks detected.

IGP1 = 4.3e-7 Torr.

Slope of OMEGA = 0.98

Tapped up manually to 35A.

Vacuum stable, initiating auto-ramp at 2.0A/min and 1.0A/min for the TGHT and TBHT respectively.

Final setpoints: TBHT = 90A, TGHT = 360A

Once final setpoints reached, will tap up manually to max 1800C [legs = 2000C]
