Design and fabrication of a novel four cell cylindrically inverted multi‐cell (CIM) solar thermionic converter for space power applications is in progress. When heated externally, the converter (8 cm diameter and 35 cm long) is capable of producing up to 492 W of electric power. The emitters operate at 2000 K while the collectors operate at 1050 K. Key components include four polycrystalline rhenium (Re) emitters, a cesium (Cs) containment vessel, and a collector trilayer. The emitters and containment vessel are both made from Re tubing. Hot Isostatic press (HIP) processing is used to produce the collector trilayer which is made up of a niobium alloy (Nb‐1%Zr) base tube, plasma sprayed aluminum oxide insulation layer, and a niobium collector tube. After machining the Re emitters are brazed to the Nb collectors. The purpose of this paper is to describe the design and fabrication of the four cell CIM which will be tested at General Atomics (GA).
