    摘要： An image pickup tube is provided with the third electrode (6, 19) to control the potential of the region which is not scanned by an electron beam in the image pickup tube target section including a substrate (1), a target electrode (2) and a photo-conductive film (3). A method for operating this image pickup tube is also disclosed. Thus, undesired image phenomena which are generated when the image pickup tube is used with a relatively high target voltage, e.g., image distortion, shading, a waterfall phenomenon and image inversion phenomenon can be suppressed, thereby realizing a high sensitivity image pickup tube. The photo-conductive film (3) is covered by a porous thin film (4).

    摘要： A target of image pickup tube, which comprises a transparent substrate (1), a transparent conductive film (2), a p-type photoconductive film (3) made mainly from amorphous Se, an n-type conductive film capable of forming a rectifying contact at the interface with the p-type photoconductive film, using the rectifying contact as a backward bias, characterized in that the p-type photoconductive film (3) contains at least a region (b) containing over 35% to 60% by weight of Te in the film thickness direction and at least a region containing 0.005 to 5% by weight of at least a material capable of forming shallow levels in the amorphous Se in the film thick­ness direction, has good after-image characteristics even if operated at a high temperature (Fig. 2).
