I've started a GS4 reheat. I have a Google Hangout set up with the various data streams and chat:
If you aren't able to join directly, let me know your email and I'll send an invite.
Today's experiment had two goals:
- Test the Tektronix PA1000 power analyzer in a variety of operating modes. Several bugs were discovered and mostly resolved, and the instrument seems to be very accurate and works well.
- Reheat the GS4.1 cell with lower H2 pressure. It had come down to around -2 psi (gauge) after two weeks idle. After debugging the system issues, we ran a number of heat cycles between 350 °C and 1250 °C in the core. Pressure behavior seen suggests a small but repeatable amount of reversible LiH decomposition.
The final heat up cycle is about to begin at 06:30 utc.
