Subject: emissivity measurements with no h.s on HP-FEBIAD container - round2

No heat shields.

Container empty.

IGP1 = 1.1e-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

Will tap up with the same parameters as last round to confirm results.

Took out of evap2 yesterday.

Aurelia took many emissivity measurements to compare with previous data - which matched up.

The dip in emissivity before going up again around ~560A could be due to oxidation of the materials.
