We started a run heated with both wire in 3.5 Bar of 75%H/25%Ar.
When we turned up the temp with both wires we saw the impedance drop first, then start to rise again. When we review Run 1 on Nov 12, we see that we were absorbing quite a bit at T_mica=156 and Current in the Celani wire = 1.7 Amps. So we decided to run both wires so that we were running 1.7 amps through the Celani wire, but heating with both wires. We will see what this does to the loading (if anything). Then we will turn off the NiCr wire and see if it continues to absorb at that current and a lower temperature. We also saw that the impedance during that run was way lower than we currently have. Maybe it has to continue to absorb more. Or maybe those parts of the wire that didn't turn black again are not changing impedance as much.
Anyway, when we stepped the power down, I noticed something in the shape of the impedance graph. It might lead us to be able to estimate the wire's operating temp. I propose that the wire drops in a second or two to the temperature inside the cell. The size of that drop might be used to calculate what temperature the wire was operating at.
The power drop:
The cell temperature drop:
So, I need help from all the wonderful commentators to figure out how to correlate this back. Any suggestions?
