The furnace core is a specially designed stress-free isothermal heat pipe, which provides a very low thermal gradient along the core working length.
The heatpipe is designed so that inner wall is not subject to thermal expansion stresses from the outer wall before the heat pipe reaches conduction temperature. The working fluid is permanently and safely sealed within the plasma-arc welded enclosure.
The Oberon 426 can be used with Blackbody Fixed Point cells.
