    Abstract: PURPOSE:To keep a resistivity distribution by attaching a solution including components capable of controlling resistivity to a ceramics after temporary firing and making its prime firing. CONSTITUTION:A molded temporally firing ceramic body 11 is provided. Providing a solution 10 capable of controlling a resistivity of the molded temporally firing ceramic body 11, it is attached to the molded temporally firing ceramic body 11. The molded temporally firing ceramic body attached with the solution for controlling its resistivity is followed by its prime firing. Through the above process, a secondary electron multiplier device can be obtained. It is formed by a ceramic semiconductor having secondary electron emission power by which different resistivity distributions are caused and also structured so as to have higher resistivity at an output terminal side than that at an input terminal side.

    Abstract: PURPOSE:To keep a funnel part of a secondary electron multiplier tube in constant position and posture and make it easy to fix the secondary electron multiplier as well as to assemble a secondary electron multiplying apparatus by installing supporting metal fittings in a predetermined fixing positions with predetermined angles in an insulating plate. CONSTITUTION:A contacting part 33, which has almost ring-like shape and whose internal circumference is along with the internal edge of a funnel part 2a of a secondary electron multiplier tube 2 and whose external edge is to be bent upon the external side of a funnel 2a, is installed. Supporting metal fittings 31, which are fixed to insulating plates 6, 7 with supporting part 34 drawn from the external circumference of the contacting part 33 and bent along with the insulating plates 6, 7 in the midways, and pressing metal fittings 32, which are fit on the funnel pat 2a of the secondary electron multiplier tube 2, welded with the supporting metal fittings 31 adjacently to the external sides near the open end of the funnel part 2a of the secondary electron multiplier tube 2, and fixing the funnel part 2a of the secondary electron multiplier tube 2 to the supporting metal fittings 31, are installed. As a result, fixing the funnel part in a certain position and posture becomes easy and assembling cost of the secondary electron multiplying apparatus is lowered and made easy.
