 A new target boat was sprayed with TaC coating and let dry, the coating appeared slightly bubbly once dried [see attached photos].

The target boat was wrapped with 3-layers of Ta-heat shield.

The boat was installed in Evap#1, chamber is currently being pumped down overnight.

Chamber was pumped down to 5.9e-6 Torr overnight.

TGHT was stepped up to 35A.

Waited 20min, vacuum consistently stable, auto-ramp initiated at 0.2A/min and max setpoint to 580A.

Good vacuum: 5e-5 Torr. Bad vacuum: 6e-5 Torr.

TGHT auto-cooldown initiated at 2.0A/min.
