For example, a vidicon type image pickup tube is constructed as shown in FIG. 1, in which a face plate 2 made of glass is sealed to the open end of a vacuum envelope 1 made of glass in the shape of a cylinder with a bottom, and a face plate 2 made of glass is sealed near the boundary. An annular signal electrode 3 is attached to. A transparent conductive layer 4 made of tin oxide or the like and an X-ray sensitive photoelectric layer 5 made of PbO or the like are sequentially formed on the inner surface of the face plate 2. The transparent conductive layer 4 and the photoconductive layer 5 constitute a so-called target, and the transparent conductive layer 4 is electrically connected to the annular signal electrode 3. Further, inside the vacuum envelope 1, there is a cathode 7 with a built-in heater 6.
The first to fourth
Grid electrodes 8 to 11 are sequentially arranged, and the heater 6 and each electrode 7 to 9 are connected to a plurality of conductive pins 17 provided through the stem 1a (however, in the figure, for convenience, they are not connected). (pictured).
Further, the first to third grid electrodes 8 to 10 are supported by insulating rods (not shown) via support elements, and the fourth grid electrode 11 is a so-called mesh electrode and faces the photoconductive layer 5. In such an image pickup tube, during operation, an electron beam emitted from the negative pole 7 is focused and polarized by a magnetic field and scans the photoconductive layer 5, and is characterized by being small, easy to use, stable in operation, and long life. have.
