Convection and radiation will tend to equalise temperature inside the reactor cavity pretty quickly regardless of where the heat source is within the cavity. Page 4,5 of Dekaflion's Hyperion product details pdf from november shows a cross-section with a horizontal cylindrical geometry and lists 40mm diameter by 100mm long.
I've been looking at the photos of the single-unit "Series A?" in the spec

which seems to be tube-like.
The pre-heater is :
Electric power preheating
Heating resistor fixture Nut: M12,
Thread: M10 x 1.25,
Pre-heat: 6 seconds,
Volts: 24,
Amps: 6,
Max operating temperature 1050oC
24x6 = 144W : are they going to run this continually?
The maximum temperatures everywhere seem to be rated at around 1000-1100 C
The Series A pre-industrial is rated at 5kW (max 10kW) -- can that be dissipated without cooling flow?
Could 5kW be reverse-engineered from the temperature profile to give a kW/cc power production rating for the "thermalization" zone
[ I'm probably doing too much thinking aloud here ... ]
Another semi-random thought : in looking up "Differential Thermal Analysis" there was a suggestion to modulate the heater power sinusoidallly, and then use Fourier anaylsis on the output to separate out the "base" and "differential" components.
