Axil, I think your concern is unfounded.

Any directly connected sensor may be unreliable and erratic because of the
production of intense RG radiation especially in a reactor without RF shielding.
The only way to get good temperature data is through remote sensing,

The discussion of color and temperature only mask the glaring reality that
an inexpensive way to be certain of thermal gain in the TP2 device is flow
calorimetry.
I think flow calorimetry with this device at these temperatures would be
problematic. For one thing, you could not see the device, which might even be
dangerous. I think the present method is better, although it may not have been
done right. It should be confirmed with the internal thermocouples.
Well, catch-22 they used an internal thermocouple - and apparently took
data from a perfect location, which could “see” down the axis of the tube,
presumably the hottest place in the system, but chose not to release the data.
What excuse can they have - other than the thermocouple data does not
support the thermography (therefore the thermocouple failed)?
Ahern proposed a calorimeter which would not compromise the integrity of
the ceramic tube.
