Subject: Temperature measurements for ARIEL  

 Friday, March 09, 2018, 11:03

LP-FEBIAD loaded into evap2 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 = 1.72e-7 Torr

 

 

IGP2 = 1.36e-7 Torr

Tapped up to TGHT = 50 A, 0.54 V; TBHT = 50 A, 0.45 V

IGP1 = 1.8e-6 Torr

IGP2 = 1.4e-6 Torr

Initiating auto ramp for TGHT at 2.0A/min up to 310A and TBHT at 1.0A/min up to 210A

IGP1 = 8.8e-8 Torr

IGP2 = 6.6e-8 Torr

TGHT = 310A, 5.06V

TBHT = 210A, 2.98 V

TGHT and TBHT will be adjusted accordingly for temperature measurements

Temperature measurements done.

Initiated auto-cool.

TGHT cooling at 2.0A/min and TBHT at 1.0A/min.
