Abstract:

Progress is reported in the development of ap paratus for simultaneous and quasi-simultaneous deposition of the constituents of S-20 photo cathodes by the mouccular beam technique. Several modifications of standard S-20 cathodes were attempted. A conducting substrate for the Cs-K-Sb photocathode has been developed. X-ray diffraction and chemical analysis experiments were conducted to establish the chemical com position of Cs-K-Sb cathodes. Development of the techniques for high energyellectron diffraction of photocathodes and low energy electron diffrac tion of single crystals has been continued. Small area shallow p-n junctions have been pre pared in germanium by diffusion and epitaxial growth for field induced phomeemission with low reverse bias currents. Author
