Abstract

PURPOSE:To avoid the unevenness of a photoelectric cathode quality by making a gap between cylindrical and metal electrodes narrowest on the side of a connection pipe and widest on its reverse side. CONSTITUTION:The feed rate of the alkali metal vapor shall be almost equalized in case of a feed passage 16 connected to the area of a connection pipe 9 where the concentration of alkali metal vapor higher in comparison with the case of a passage 17 on the reverse side of the connection pipe 9 where the concentration is low. For this purpose, when a cylindrical electrode 4 is integrated with a metal electrode 3, its bottom end shall be slanted in such that, its gap against the inner bottom 12 of the metal electrode 3 is smallest on the side of the connection pipe 9 and largest on its reverse side.
