Abstract

PURPOSE:To prevent deterioration of characteristic of a camera tube arising from deformation of its beam disc, by fixedly holding the beam disc to the second grid electrode with an auxiliary ring. CONSTITUTION:A relatively thick reinforcing ring 4 is placed on a beam disc 3 in the second grid 2, and the beam disc 3 is forcibly pressed by said reinforcing ring 4 and fixed to the second grid electrode 2. In this way, thermal deformation of the beam disc 3 can be prevented to eliminate misalignment of a position for the electrode.
