LP-FEBIAD loaded into evap2 this morning and pumped down.

Temperature measurements of the ionizer will be done by Fernando for ARIEL development.

Ta foil covering side holes on heat shield so no temp measurements can be done using OMEGA on side ports of evaporator as per request of Fernando

No Ta heat shields on container.

HS water valves opened, no leaks detected.

IGP1 = 2.3e-6 Torr

IGP2 = 1.7e-6 Torr

Tapped up to TGHT = 50A, 0.30V; TBHT = 50A, 0.59V

IGP1 = 1.8e-6 Torr

IGP2 = 1.4e-6 Torr

Initiating auto ramp for TGHT at 2.0A/min up to 350A and TBHT at 1.0A/min up to 210A

IGP1 = 7.6e-7 Torr

IGP2 = 6.4e-7 Torr

TGHT = 350A, 5.85V

TBHT = 210A, 3.02V

TGHT and TBHT will be adjusted accordingly for temperature measurements...
