It is very unfortunately that it happened now.
Don't know if you have still enough Durapot to make a new cylinder.
Nevertheless you provided the data of your previous measurements. Thanks for that.
Currently I am in the process doing FEM simulations on your rod and have discovered that there needs to be adaptions with respect to the thermal conductivity curve for Durapot .
This hopefully will bring measured data and the simulations more in line, but the current results are not too far off either.
I am however running out of time since I will be a few weeks away to Italy.
So it may be some time before I can provide a new update.
It is unfortunate that the Cylinder is dead, but I suppose I will make another. I am considering whether I should change anything or make the new one the same. I have a spare coil and plenty of Durapot, and some new thermocouples here.
At least I was able to double-check the data from before, and the older data seems pretty solid. I also now have better data on the controller power consumption.
I am heading out for a while also quite soon, so probably no new experiments for a month, even if I get a new cylinder completed over the next week. I will compile the data I have in the meantime.
