Embodiment Construction
[0041] below, with Figure 1 The ideal embodiment of the photomultiplier tube of the present invention will be described in detail.
[0042] Fig. 1 is a perspective view showing a photomultiplier tube according to a first embodiment of the present invention, and Fig. 2 is a cross-sectional view of Fig. 1 . The photomultiplier tube 1 shown in these drawings has a side tube 2 made of metal (for example, made of Kovar (Kovar) iron-nickel-cobalt alloy or stainless steel) approximately in the shape of a square column, and the opening on one side of the side tube 2 is A light-receiving panel 3 made of glass is welded and fixed on the end 2A. On the inner surface of the light-receiving panel 3, a photoelectric surface 3a for converting light into electrons is formed. The antimony deposited on the surface reacts to form. In addition, a lever plate 4A made of metal (for example, made of Kovar metal or stainless steel) is welded and fixed to the opening end 2B of the side pipe 2 . Thu...
