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.
