The Cool Transfer Line (CTL) test target is installed for thermal tests. Drawing number is ITD0431 REV A.
Thermocouple channels are as follows:
T1: Cu block on CTL
T2: Heat Shield above CTL
T3: Heat Shield cooling water Supply
T4: Heat Shield cooling water Return
Cooling water is in Evap2 supplied to the cooling line that goes directly to the area on the Heat Shield above the CTL.

The CTL test target was installed again for a second thermal test. CTL block fastened to HS with 1 in lbs. A small piece of Ta-foil of 0.001" thickness was used between the CTL Cu-block and the Ta transfer line to reduce the heat transfer..
Thermocouples were re-attached to CTL and Heat Shield (see above for channels #s).

Chamber was pumped down to 2 e-7 Torr. HS water valve opened and no leaks were detected.
TGHT and TBHT are ramping up to 850A and 300A at 2A/min, respectively.
RGA is running...

TGHT/TBHT reached to max currents.
See attachment #1 for temperature and RGA measurements.
Cooling down in process... 5A/min.
