Materials selection and performance for thermionic diode application in fusion reactor systems is examined. The volumetric heating, atom displacement damage and He production due to neutron attenuation in four diode designs are calculated with ANISN-W and relevant kerma factors. The preferred design includes a graphite or silicon carbide first wall/susceptor, a refractory metal emitter and refractory metal collector.
