Abstract : Uniform work functions of thermionic converters were investigated. The performance of cylindrical converters which have emitters with uniform work function surface was evaluated. Chemical vapor deposition techni ues were developed for the fabrication of nonplanar emitters of practical design which have improved uniformity of work function over the uniformity of work function of standard polycrystalline emitters. The development of thermionic converters having emitters of improved uniformity of work function may result in increased efficiency and power density. A converter test stand was assembled, equipment associated with the test stand was calibrated, and deposition samples were fabricated. (Author)
