One thermocouple was not welded on correctly and is not working.
Cooling evap2 back down, to remove target and re-weld thermocouple.
Once thermocouple replaced, will ramp back up and continue with tests/ conditioning of target.

Monday, March 14, 2016, 13:12: Stopped turbo pump

After EVAP2 was vented the thermocouple problem was fixed: it was the wire at on connector inside the box not making proper contact. The lid of the heat shield was also replaced since the one initially mounted had no holes, so one couldn't see the center block. Restarted pumping down at 4:30pm. Just started again the autoramp program: TGHT set to 300A (for the time being) and TBHT to 230A. Temperature measurements will resume tomorrow morning. |
